 # Contributing code to Element
 
 Element follows the same pattern as the [matrix-js-sdk](https://github.com/matrix-org/matrix-js-sdk/blob/develop/CONTRIBUTING.md).
+
+# Contributing to Element Call
+
+Element Call is a native Matrix video conferencing application built on
+[MatrixRTC (MSC4143)](https://github.com/matrix-org/matrix-spec-proposals/pull/4143)
+and [LiveKit](https://livekit.io/). It runs in multiple deployment contexts — as a
+standalone web app and as a widget embedded in Element Web, Element X iOS, and
+Element X Android. It is also the primary R&D foundation for MatrixRTC, which means
+its architecture, maintainability, and flexibility are held to a high standard.
+
+We welcome contributions from the community. This document explains how to
+contribute effectively so that both you and the maintainers get the best outcome.
+
+## Issue First Policy
+
+> [!IMPORTANT]
+> Before writing a single line of code for a new feature or UI change, you **must**
+> open an issue and have the approach agreed with the maintainers.
+>
+> **We will not review or merge feature or UI pull requests that arrive without a
+> corresponding, pre-approved issue.**
+
+This is not gatekeeping — it's how we prevent wasted effort on both sides. Element
+Call must work correctly across multiple deployment contexts and meet specific product
+and design requirements. It is also a fast-moving codebase that underpins ongoing
+MatrixRTC development. A PR that looks reasonable in isolation can easily conflict
+with in-progress work, planned architecture changes, or design decisions that haven't
+been publicly documented yet.
+
+The issue is where we resolve all of that **before** anyone writes code.
+
+**Bug fixes** are no exception — most confirmed bugs should already have an issue anyways, existing issues that are marked as bugs have an implicit maintainer approval. If the solution for the bug is controversial it is highly recommended to discuss the approach in the issue before opening a PR.
+
+## Contribution Workflow
+
+1. **Open an issue** using the [Enhancement request](https://github.com/element-hq/element-call/issues/new?template=enhancement.yml) template.
+2. **Wait for feedback.** A maintainer will comment on the issue **within two weeks**. The use case and approach will get dicussed.
+   This may involve questions, suggestions, or a request to adjust scope.
+   This also allows to bring design and product into the loop before code gets created.
+3. **Get a green light.** Wait for explicit approval from a maintainer before starting
+   implementation.
+4. **Implement.** Write the code against the agreed approach.
+5. **Open a PR.** Link to the issue in your PR description and satisfy the checklist
+   in the PR template.
+
+## Code Quality
+
+Element Call moves fast and the codebase must stay clean and maintainable.
+
+- **Take responsibility for AI-generated code.** AI tools can be a useful aid, but we expect all the generated code to be understood and reasoned about by the contributor. Questions by the maintainers should be answered without just forwarding them to AI. The maintainers also have access to AI tools. If your contribution is just transporting messages between LLM <-> maintaines all our time is better used if the maintainers decide to interact with AI for this specific problem by themselves.
+- **Think across deployment contexts.** Changes must work correctly in both standalone
+  and widget modes. Consider how your change interacts with Element Web, Element X
+  iOS, and Element X Android.
+- **Write tests.** New functionality should be covered by tests. Where it is feasible,
+  existing uncovered code touched by your PR should also gain tests.
+
+## Contributor License Agreement
+
+All contributors must sign the
+[Element Contributor License Agreement](https://cla-assistant.io/element-hq/element-call)
+before their contribution can be merged. The CLA assistant bot will prompt you
+automatically when you open a PR.
+
+## Getting Help
+
+The best place to ask questions about Element Call development is the MatrixRTC room:
+
+**[#matrixRtc:matrix.org](https://matrix.to/#/#matrixrtc:matrix.org)**

-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<https://www.gnu.org/licenses/>.

-Group calls with WebRTC that leverage [Matrix](https://matrix.org) and an open-source WebRTC toolkit from [LiveKit](https://livekit.io/).
+[🎬 Live Demo 🎬](https://call.element.io)
 
-For prior version of the Element Call that relied solely on full-mesh logic, check [`full-mesh`](https://github.com/element-hq/element-call/tree/full-mesh) branch.
+The world's first 🌐 decentralized and 🤝 federated video conferencing solution
+powered by **the Matrix protocol**.
 
-![A demo of Element Call with six people](demo.jpg)
+## 📌 Overview
 
-To try it out, visit our hosted version at [call.element.io](https://call.element.io). You can also find the latest development version continuously deployed to [call.element.dev](https://call.element.dev/).
+**Element Call** is a native Matrix video conferencing application developed by
+[Element](https://element.io/), designed for **secure**, **scalable**,
+**privacy-respecting**, and **decentralized** video and voice calls over the
+Matrix protocol. Built on **MatrixRTC**
+([MSC4143](https://github.com/matrix-org/matrix-spec-proposals/pull/4143)), it
+utilizes
+**[MSC4195](https://github.com/hughns/matrix-spec-proposals/blob/hughns/matrixrtc-livekit/proposals/4195-matrixrtc-livekit.md)**
+with **[LiveKit](https://livekit.io/)** as its backend.
 
-## Host it yourself
+![A demo of Element Call with six people](demo.gif)
 
-Until prebuilt tarballs are available, you'll need to build Element Call from source. First, clone and install the package:
+You can find the latest development version continuously deployed to
+[call.element.dev](https://call.element.dev/).
 
-```
-git clone https://github.com/element-hq/element-call.git
-cd element-call
-yarn
-yarn build
-```
+> [!NOTE]
+> For prior version of the Element Call that relied solely on full-mesh logic,
+> check [`full-mesh`](https://github.com/element-hq/element-call/tree/full-mesh)
+> branch.
 
-If all went well, you can now find the build output under `dist` as a series of static files. These can be hosted using any web server that can be configured with custom routes (see below).
+## ✨ Key Features
 
-You may also wish to add a configuration file (Element Call uses the domain it's hosted on as a Homeserver URL by default,
-but you can change this in the config file). This goes in `public/config.json` - you can use the sample as a starting point:
+✅ **Decentralized & Federated** – No central authority; works across Matrix
+homeservers.  
+✅ **End-to-End Encrypted** – Secure and private calls.  
+✅ **Standalone & Widget Mode** – Use as an independent app or embed in Matrix

+## 🚀 Deployment & Packaging Options
 
-Because Element Call uses client-side routing, your server must be able to route any requests to non-existing paths back to `/index.html`. For example, in Nginx you can achieve this with the `try_files` directive:
+Element Call is developed using the
+[Matrix js-sdk](https://github.com/matrix-org/matrix-js-sdk) with Matroska mode.
+This allows the app to run either as a Standalone App directly connected to a
+homeserver with login interfaces or it can be used as a widget within a Matrix
+client.
 
-```
-server {
-    ...
-    location / {
-        ...
-        try_files $uri /$uri /index.html;
-    }
-}
-```
+### 🖥️ Standalone Mode
 
-By default, the app expects you to have a Matrix homeserver (such as [Synapse](https://matrix-org.github.io/synapse/latest/setup/installation.html)) installed locally and running on port 8008. If you wish to use a homeserver on a different URL or one that is hosted on a different server, you can add a config file as above, and include the homeserver URL that you'd like to use.
+<p align="center">
+  <img src="./docs/element_call_standalone.drawio.png" alt="Element Call in Standalone Mode">
+</p>
 
-Element Call requires a homeserver with registration enabled without any 3pid or token requirements, if you want it to be used by unregistered users. Furthermore, it is not recommended to use it with an existing homeserver where user accounts have joined normal rooms, as it may not be able to handle those yet and it may behave unreliably.
+In Standalone mode, Element Call operates as an independent, full-featured video
+conferencing web application, enabling users to join or host calls without
+requiring a separate Matrix client.
 
-Therefore, to use a self-hosted homeserver, this is recommended to be a new server where any user account created has not joined any normal rooms anywhere in the Matrix federated network. The homeserver used can be setup to disable federation, so as to prevent spam registrations (if you keep registrations open) and to ensure Element Call continues to work in case any user decides to log in to their Element Call account using the standard Element app and joins normal rooms that Element Call cannot handle.
+### 📲 In-App Calling (Widget Mode in Messenger Apps)
 
-## Configuration
+When used as a widget 🧩, Element Call is solely responsible for the core calling
+functionality (MatrixRTC). Authentication, event handling, and room state
+updates (via the Client-Server API) are handled by the hosting client.
+Communication between Element Call and the client is managed through the widget
+API.
 
-There are currently two different config files. `.env` holds variables that are used at build time, while `public/config.json` holds variables that are used at runtime. Documentation and default values for `public/config.json` can be found in [ConfigOptions.ts](src/config/ConfigOptions.ts).
+<p align="center">
+  <img src="./docs/element_call_widget.drawio.png" alt="Element Call in Widget Mode">
+</p>
 
-If you're using [Synapse](https://github.com/element-hq/synapse/), you'll need to additionally add the following to `homeserver.yaml` or Element Call won't work:
+Element Call can be embedded as a widget inside apps like
+[**Element Web**](https://github.com/element-hq/element-web) or **Element X
+([iOS](https://github.com/element-hq/element-x-ios),
+[Android](https://github.com/element-hq/element-x-android))**, bringing
+**MatrixRTC** capabilities to messenger apps for seamless decentralized video
+and voice calls within Matrix rooms.
 
-```
-experimental_features:
-    msc3266_enabled: true
-```
+> [!IMPORTANT]
+> Embedded packaging is recommended for Element Call in widget mode!
 
-MSC3266 allows to request a room summary of rooms you are not joined.
-The summary contains the room join rules. We need that to decide if the user gets prompted with the option to knock ("ask to join"), a cannot join error or the join view.
+### 📦 Element Call Packaging
 
-Element Call requires a Livekit SFU behind a Livekit jwt service to work. The url to the Livekit jwt service can either be configured in the config of Element Call (fallback/legacy configuration) or be configured by your homeserver via the `.well-known`.
-This is the recommended method.
+Element Call offers two packaging options: one for standalone or widget
+deployment, and another for seamless widget-based integration into messenger
+apps. Below is an overview of each option.
 
-The configuration is a list of Foci configs:
+**Full Package** – Supports both **Standalone** and **Widget** mode. It is
+hosted as a static web page and can be accessed via a URL when used as a widget.
+
+<p align="center">
+  <img src="./docs/full_package.drawio.png" alt="Element Call Full Package">
+</p>
+
+**Embedded Package** – Designed specifically for **Widget mode** only. It is
+bundled with a messenger app for seamless integration and this is the
+recommended method for embedding Element Call.
+
+<p align="center">
+  <img src="./docs/embedded_package.drawio.png" alt="Element Call Embedded Package">
+</p>
+
+For more details on the packages, see the
+[Embedded vs. Standalone Guide](./docs/embedded_standalone.md).
+
+## 🛠️ Self-Hosting
+
+For operating and deploying Element Call on your own server, refer to the
+[**Self-Hosting Guide**](./docs/self_hosting.md).
+
+## 🧭 MatrixRTC Backend Discovery and Selection
+
+For proper Element Call operation each site deployment needs a MatrixRTC backend
+setup as outlined in the [Self-Hosting Guide](./docs/self_hosting.md). A typical
+federated site deployment for three different sites A, B and C is depicted below.
+
+<p align="center">
+  <img src="./docs/Federated_Setup.drawio.png" alt="Element Call federated setup">
+</p>
+
+### Backend Discovery
+
+The MatrixRTC backend (according to
+[MSC4143](https://github.com/matrix-org/matrix-spec-proposals/pull/4143)) is
+announced by the Matrix site's `.well-known/matrix/client` file and discovered
+via the `org.matrix.msc4143.rtc_foci` key, e.g.:
 
 ```json
 "org.matrix.msc4143.rtc_foci": [
     {
         "type": "livekit",
-        "livekit_service_url": "https://someurl.com"
-    },
-     {
-        "type": "livekit",
-        "livekit_service_url": "https://livekit2.com"
-    },
-    {
-        "type": "another_foci",
-        "props_for_another_foci": "val"
+        "livekit_service_url": "https://matrix-rtc.example.com/livekit/jwt"
     },
 ]
 ```
 
-## Translation
+where the format for MatrixRTC using LiveKit backend is defined in
+[MSC4195](https://github.com/hughns/matrix-spec-proposals/blob/hughns/matrixrtc-livekit/proposals/4195-matrixrtc-livekit.md).
+In the example above Matrix clients do discover a focus of type `livekit` which
+points them to a [MatrixRTC Authorization Service](https://github.com/element-hq/lk-jwt-service)
+via `livekit_service_url`.

+### Backend Selection
 
-## Development
+- Each call participant proposes their discovered MatrixRTC backend from
+  `org.matrix.msc4143.rtc_foci` in their `org.matrix.msc3401.call.member` state event.
+- For the **LiveKit** MatrixRTC backend
+  ([MSC4195](https://github.com/hughns/matrix-spec-proposals/blob/hughns/matrixrtc-livekit/proposals/4195-matrixrtc-livekit.md)),
+  the **first participant who joined the call** defines which backend will be used for this call via
+  the `foci_preferred` key in their `org.matrix.msc3401.call.member` state event.
+- During the actual call join flow, the **[MatrixRTC Authorization Service](https://github.com/element-hq/lk-jwt-service)**
+  provides the client with the **LiveKit SFU WebSocket URL** and an
+  **access JWT token** in order to exchange media via WebRTC.
+
+The example below illustrates how backend selection works across **Matrix
+federation**, using the setup from sites A, B, and C. It demonstrates backend
+selection for **Matrix rooms 123 and 456**, which include users from different
+homeservers.

+- [Corepack](https://github.com/nodejs/corepack) (not bundled with Node.js anymore starting from 25.0.0)
+- Docker client and runtime + Docker Compose (for the backend)
+  - On macOS you can install everything with `brew install colima docker docker-compose`
 
 ### Frontend
 
-Element Call is built against [matrix-js-sdk](https://github.com/matrix-org/matrix-js-sdk/pull/2553). To get started, clone, install, and link the package:
+To get started clone and set up this project:
 
-```
-git clone https://github.com/matrix-org/matrix-js-sdk.git
-cd matrix-js-sdk
-yarn
-yarn link
-```
-
-Next, we can set up this project:
-
-```
+```sh
 git clone https://github.com/element-hq/element-call.git
 cd element-call
-yarn
-yarn link matrix-js-sdk
+corepack enable
+pnpm install
 ```
 
+To use it, create a local config by, e.g.,
+`cp ./config/config.devenv.json ./public/config.json` and adapt it if necessary.
+The `config.devenv.json` config should work with the backend development
+environment as outlined in the next section out of box.
+
 You're now ready to launch the development server:
 
+```sh
+pnpm dev
 ```
-yarn dev
-```
+
+See also:
+
+- [Developing with linked packages](./docs/linking.md)
 
 ### Backend
 
-A docker compose file is provided to start a LiveKit server and auth
-service for development. These use a test 'secret' published in this
-repository, so this must be used only for local development and
-**_never be exposed to the public Internet._**
+A docker compose file `dev-backend-docker-compose.yml` is provided to start the
+whole stack of components which is required for a local development environment
+including federation:
 
-To use it, add a SFU parameter in your local config `./public/config.json`:
-(Be aware, that this is only the fallback Livekit SFU. If the homeserver
-advertises one in the client well-known, this will not be used.)
+- Minimum Synapse Setup (servernames: `synapse.m.localhost`, `synapse.othersite.m.localhost`)
+- MatrixRTC Authorization Service (Note: requires Federation API and hence a TLS reverse proxy)
+- Minimum LiveKit SFU setup using dev defaults for config
+- Minimum `localhost` Certificate Authority (CA) for Transport Layer Security (TLS)
+  - Hostnames: `m.localhost`, `*.m.localhost`, `*.othersite.m.localhost`
+  - Add [./backend/dev_tls_local-ca.crt](./backend/dev_tls_local-ca.crt) to your web browser's trusted
+    certificates
+- Minimum TLS reverse proxy for
+  - Synapse homeserver: `synapse.m.localhost` and `synapse.othersite.m.localhost`
+  - MatrixRTC backend: `matrix-rtc.m.localhost` and `matrix-rtc.othersite.m.localhost`
+  - Local Element Call development `call.m.localhost` via `pnpm dev --host `
+  - Element Web `app.m.localhost` and `app.othersite.m.localhost`
+  - Note certificates will expire on Thr, 20 September 2035 14:27:35 CEST
 
-```json
-"livekit": {
-  "livekit_service_url": "http://localhost:7881"
-},
+These use a test 'secret' published in this repository, so this must be used
+only for local development and **_never be exposed to the public Internet._**
+
+Make sure your Docker runtime is running (e.g. via `colima start`) and then start
+the backend components:
+
+```sh
+pnpm backend
+# or for podman-compose:
+# podman-compose -f dev-backend-docker-compose.yml up
 ```
 
-Run backend components:
+> [!NOTE]
+> To ensure your local development frontend functions properly, you’ll need to
+> add certificate exceptions in your browser for `https://localhost:3000`,
+> `https://matrix-rtc.m.localhost/livekit/jwt/healthz` and
+> `https://synapse.m.localhost/.well-known/matrix/client`. This can be either
+> done by adding the minimum localhost CA
+> ([./backend/dev_tls_local-ca.crt](./backend/dev_tls_local-ca.crt)) to your web
+> browser's trusted certificates or by simply copying and pasting each URL into
+> your browser’s address bar and follow the prompts to add the exception.
+
+### Updating snapshots
+
+To update snapshots used in tests, use Vitest's `-u` flag, e.g.:
+
+```sh
+pnpm test DeveloperSettingsTab -u
+```
+
+### Playwright tests
+
+Our Playwright tests run automatically as part of our CI along with our other
+tests, on every pull request.
+
+You may need to follow instructions to set up your development environment for
+running Playwright by following
+<https://playwright.dev/docs/browsers#install-browsers> and
+<https://playwright.dev/docs/browsers#install-system-dependencies>.
+
+However the Playwright tests are run, an element-call instance must be running
+on https://localhost:3000 (this is configured in `playwright.config.ts`) - this
+is what will be tested.
+
+The local backend environment should be running for the test to work:
+`pnpm backend`
+
+There are a few different ways to run the tests yourself. The simplest is to
+run:
+
+```shell
+pnpm run test:playwright
+```
+
+This will run the Playwright tests once, non-interactively.
+
+There is a more user-friendly way to run the tests in interactive mode:
+
+```shell
+pnpm run test:playwright:open
+```
+
+The easiest way to develop new test is to use the codegen feature of Playwright:
+
+```shell
+npx playwright codegen
+```
+
+This will record your action and write the test code for you. Use the tool bar
+to test visibility, text content and clicking.
+
+##### Investigate a failed test from the CI
+
+In the failed action page, click on the failed job, then scroll down to the
+`upload-artifact` step. You will find a link to download the zip report, as per:
 
 ```
-yarn backend
+Artifact playwright-report has been successfully uploaded! Final size is 1360358 bytes. Artifact ID is 2746265841
+Artifact download URL: https://github.com/element-hq/element-call/actions/runs/13837660687/artifacts/2746265841

+Unzip the report then use this command to open the report in your browser:
+
+```shell
+npx playwright show-report ~/Downloads/playwright-report/

+When running `pnpm backend` the latest element-web develop will be deployed and served on `http://localhost:8081`.
+In a development environment, you might prefer to just use the `element-web` repo directly, but this setup is useful for CI/CD testing.
+
+## Setup
+
+The element-web configuration is modified to:
+
+- Enable to use the local widget instance (`element_call.url` https://localhost:3000).
+- Enable the labs features (`feature_group_calls`, `feature_element_call_video_rooms`).

+# Developer help
+
+## Testing on Mobile Devices
+
+When developing Element Call locally, you may want to test on physical mobile devices (iOS/Android)
+on the same WiFi network.
+
+**Known Limitations:** For now this setup allows to use your local EC server but not yet the SFUs and Synapses.
+
+### Prerequisites
+
+1. **Start the dev server**
+
+   ```bash
+   pnpm dev
+   ```
+
+Check the output for the `➜  Network` (this will contain the local IP address of your laptop)
+
+```
+  ➜  Local:   https://m.localhost:3000/                                                                                                                                                                 12:06:48
+  ➜  Local:   https://vite.m.localhost:3000/                                                                                                                                                            12:06:48
+  ➜  Local:   https://vite.othersite.m.localhost:3000/                                                                                                                                                  12:06:48
+  ➜  Local:   https://vite.nip.io:3000/                                                                                                                                                                 12:06:48
+  ➜  Network: https://192.168.0.122:3000/
+```
+
+2. **Transfer the CA certificate to your phone**
+
+   The file is located at `backend/dev_tls_local-ca.crt`. Transfer it via:
+   - Matrix room
+   - AirDrop for iphone
+
+### IOS Setup
+
+**Install the certificate profile on iPhone**
+
+- Open the `dev_tls_local-ca.crt` file on your iPhone
+- You'll see "Profile Downloaded"
+- Go to **Settings → General → VPN & Device Management** (or **Settings → General → Profiles**)
+- Tap the "Element Call Dev CA" profile
+- Tap **Install** and enter your passcode
+- Confirm by tapping **Install** again
+
+**Enable full trust (Critical!)**
+
+- Go to **Settings → General → About → Certificate Trust Settings**
+- Under "Enable Full Trust for Root Certificates"
+- Toggle **ON** for "Element Call Dev CA"
+- Confirm the security warning
+
+**Access Element Call**
+
+Find your laptop's IP address (e.g., `192.168.0.122`) and use one of these URLs in Safari to validate:
+
+```
+https://192-168-0-122.nip.io:3000/
+```
+
+**For Element X iOS Developer Tools**
+
+In Element X's developer settings, set the Element Call URL to the nip.io url (replace . with - in the IP address):
+
+```
+https://192-168-0-122.nip.io:3000/room
+```
+
+### Android Setup
+
+**Transfer the CA certificate to your Android device**
+
+The file is located at `backend/dev_tls_local-ca.crt`.
+
+**Install the certificate**
+
+This might vary by Android version and manufacturer, but generally:
+
+- Open **Settings** search for "CA Certificate"/"Certificate"
+- Tap **Install a certificate** or **Install from storage**
+- Select **CA certificate**
+- Confirm the security warning
+- Navigate to and select the `dev_tls_local-ca.crt` file
+- Give it a name like "Element Call Dev CA"
+
+**Access Element Call**
+
+Find your laptop's IP address (e.g., `192.168.0.122`) and use one of these URLs in Chrome to validate:
+
+```
+https://192-168-0-122.nip.io:3000/
+```
+
+**For Element X Android Developer Tools**
+
+In Element X's developer settings, set the Element Call URL to the nip.io url (replace . with - in the IP address):
+
+```
+https://192-168-0-122.nip.io:3000/room
+```
+
+### Why nip.io?
+
+[nip.io](https://nip.io) is a free wildcard DNS service that automatically resolves domain names containing IP addresses. For example, `192-168-0-122.nip.io` automatically resolves to `192.168.0.122`. This means:
+
+- No need to regenerate certificates when your laptop's IP changes
+- Works from any device without DNS configuration
+- iOS/Android treat it as a proper domain name, not an IP address
+- One-time certificate setup works for all future IP addresses
+
+> [!IMPORTANT]
+> Make sure your network router doesn't enforce DNS rebinding protection (which will
+> break nip.io). If it does, try allow-listing nip.io in your router's administration interface.

+A few aspects of Element Call's interface can be controlled through a global API on the `window`.
+
+## Picture-in-picture
 
 - `controls.canEnterPip(): boolean` Determines whether it's possible to enter picture-in-picture mode.
 - `controls.enablePip(): void` Puts the call interface into picture-in-picture mode. Throws if not in a call.
 - `controls.disablePip(): void` Takes the call interface out of picture-in-picture mode, restoring it to its natural display mode. Throws if not in a call.
+- `controls.onPipMediaOrientationUpdate: ((orientation: "landscape"|"portrait") => void) | undefined` Callback called whenever the PiP media orientation changes.
+  The client should track this value to already initiate the pip in the right orientation.
+  It should update the orientation of the current Pip window when called.
+
+## Audio devices
+
+On mobile platforms (iOS, Android), web views do not reliably support selecting audio output devices such as the main speaker, earpiece, or headset. To address this limitation, the following functions allow the hosting application (e.g., Element Web, Element X) to manage audio devices via exposed JavaScript interfaces. These functions must be enabled using the URL parameter `controlledAudioDevices` to take effect.
+
+- `controls.setAvailableAudioDevices(devices: { id: string, name: string, forEarpiece?: boolean, isEarpiece?: boolean isSpeaker?: boolean, isExternalHeadset?: boolean }[]): void` Sets the list of available audio outputs. `forEarpiece` is used on iOS only.
+  It flags the device that should be used if the user selects earpiece mode. This should be the main stereo loudspeaker of the device.
+- `controls.onAudioDeviceSelect: ((id: string) => void) | undefined` Callback called whenever the user or application selects a new audio output.
+- `controls.setAudioDevice(id: string): void` Sets the selected audio device in Element Call's menu. This should be used if the OS decides to automatically switch to Bluetooth, for example.
+- `controls.setAudioEnabled(enabled: boolean)` Enables/disables all audio output from the application. Output is enabled by default.
+- `controls.onAudioPlaybackStarted: ((id: string) => void) | undefined`: This will be called the first time we start
+  playing audio in the webview. It can be helpful to do device setup on the native app when the webviews audio is ready.
+  In particular android is using it to setup the output channel so that the call volume can
+  be controlled by the hardware volume rocker.
+
+## Element Call button delegation
+
+Callbacks for buttons in EC that are handled by the native application
+
+- `showNativeAudioDevicePicker: (() => void) | undefined`. Callback called whenever the user presses the output button in the settings menu.
+  This button is only shown on iOS. (`/iPad|iPhone|iPod|Mac/.test(navigator.userAgent)`)
+- `onBackButtonPressed: (() => void) | undefined`. Callback when the webview detects a tab on the header's back button.

-## Embedded vs standalone mode
-
-Element call is developed using the js-sdk with matroska mode. This means the app can run either as a standalone app directly connected to a homeserver providing login interfaces or it can be used as a widget.
-
-As a widget the app only uses the core calling (matrixRTC) parts. The rest (authentication, sending events, getting room state updates about calls) is done by the hosting client.
-Element Call and the hosting client are connected via the widget api.
-
-Element call detects that it is run as a widget if a widgetId is defined in the url parameters. If `widgetId` is present element call will try to connect to the client via the widget postMessage api using the parameters provided in [Url Format and parameters
-](./url-params.md).

+
+### Using the embedded package within a messenger app
+
+Currently the best way to understand the necessary steps is to look at the implementations in the Element Messenger apps: [Web](https://github.com/element-hq/element-web/pull/29309), [iOS](https://github.com/element-hq/element-x-ios/pull/3939) and [Android](https://github.com/element-hq/element-x-android/pull/4470).
+
+The basics are:
+
+1. Add the appropriate platform dependency as given for a [release](https://github.com/element-hq/element-call/releases), or use the embedded tarball. e.g. `npm install @element-hq/element-call-embedded@0.9.0`
+2. Include the assets from the platform dependency in the build process. e.g. copy the assets during a [Webpack](https://github.com/element-hq/element-web/blob/247cd8d56d832d006d7dfb919d1042529d712b59/webpack.config.js#L677-L682) build.
+3. Use the `index.html` entrypoint of the imported assets when you are constructing the WebView or iframe. e.g. using a [relative path in a webapp](https://github.com/element-hq/element-web/blob/247cd8d56d832d006d7dfb919d1042529d712b59/src/models/Call.ts#L680), or on the the Android [WebViewAssetLoader](https://github.com/element-hq/element-x-android/blob/fe5aab6588ecdcf9354a3bfbd9e97c1b31175a8f/features/call/impl/src/main/kotlin/io/element/android/features/call/impl/utils/DefaultCallWidgetProvider.kt#L20)
+4. Set any of the [embedded-only URL parameters](./url_params.md#embedded-only-parameters) that you need.
+
+## Widget vs standalone mode
+
+Element Call is developed using the [js-sdk](https://github.com/matrix-org/matrix-js-sdk) with matroska mode. This means the app can run either as a standalone app directly connected to a homeserver providing login interfaces or it can be used as a widget within a Matrix client.
+
+As a widget, the app only uses the core calling (MatrixRTC) parts. The rest (authentication, sending events, getting room state updates about calls) is done by the hosting client.
+Element Call and the hosting client are connected via the widget API.
+
+Element Call detects that it is run as a widget if `widgetId` is defined in the url parameters. If `widgetId` is present then Element Call will try to connect to the client via the widget postMessage API using the parameters provided in [Url Format and parameters
+](./url_params.md).

+## Quickstart guide
+
+Run:
+
+```bash
+./scripts/setup-linking.sh
+```
+
+Read the script output:
+
+```
+Setup complete.
+Update: .links.cjs to your liking
+Run: 'pnpm links:on' to test your .links.cjs
+Run: 'git commit' with links enabled to test the git pre-commit hook.
+Run: 'pnpm links:off' to be able to commit again
+Run: 'git config --local core.hooksPath ""' to allow committing with linking (not recommended)
+Run: 'rm links.cjs' & 'git config --local core.hooksPath ""' to fully revert what this script did
+```
+
+# Developing with linked packages
+
+If you want to make changes to a package that Element Call depends on and see those changes applied in real time, you can create a link to a local copy of the package. `pnpm` has a command for this (`pnpm link`), but it's not recommended to use it as it ends up modifying package.json with details specific to your development environment.
+
+Instead, create a file named `.links.cjs` in the Element Call project directory (or run `./scripts/setup-linking.sh` to create a template), listing the names and paths of any dependencies you want to link. For example:
+
+```cjs
+// Packages to link to local checkouts
+module.exports = {
+  "matrix-js-sdk": "../your/path/matrix-js-sdk",
+  "matrix-widget-api": "../your/path/matrix-widget-api",
+};
+```
+
+Then run `pnpm links:on`. (this will activate the pnpm file + run `pnpm install` to setup the linking)
+
+## Hooks
+
+Changes in `.links.cjs` will also update `pnpm-lock.yaml` when `pnpm install` is executed. The lockfile will then contain the local
+version of the package which would not work on others dev setups or the github CI.
+
+One always needs to remove the pnpm `readPackage` script (the `.pnpmfile.cjs`) and run:
+
+```bash
+pnpm install
+```
+
+before committing a change.
+
+To make this less of a foot gun we added a git hook.
+A `pre-commit` hook will check if linking is currently used. If it detects
+a `.pnpmfile.cjs` file it will abort the commit with an explanatory message.
+You will then need to run `pnpm links:off` and commit again.
+
+To activate the hooks configure git with (when using the setup script (`./scripts/setup-linking.sh`) this is already done):
+
+```bash
+git config --local core.hooksPath .githooks
+```
+
+This will add the hook path for this repository only to .gihooks. which is a tracked (by git) folder containing the pre-commit hook.
+

+### Why do we not enable .pnpmfile.cjs by default
+
+Background: The presence of the `.pnpmfile.cjs` adds a field to the `pnpm-lock.yaml` called: `pnpmfileChecksum`. This field is a checksum of the content of the `.pnpmfile.cjs` file.
+`pnpm install --frozen-lockfile` **fails** if there is a `.pnpmfile.cjs` but no `pnpmfileChecksum` or vice versa (or on mismatch).
+
+_TLDR: running with `--ignore-pnpmfile` will fail if `pnpmfileChecksum` is present._
+
+#### `pnpmfileChecksum` + renovate bot
+
+When the renovate bot creates a PR it runs `pnpm install --ignore-pnpmfile`. This means that the `pnpmfileChecksum` in the lockfile will be **empty**.
+This breaks builds that **don't** ignore the `.pnpmfile.cjs`-file. (CI that runs on the renovate PR)
+From here we have two possible paths:
+
+- ignore `.pnpmfile.cjs` in all CI builds (CI will also fail if we accidently add it locally).
+- fixup the `pnpm-lock.yaml` in the renovate PR to contain the correct `pnpmfileChecksum`.
+
+Ignoring in all CI builds means that CI will always fail if we enable the linking system.
+This is annoying but can be worked around with the git hook we provide that at least lets us know that we are
+commiting with enabled linking.
+Only if we remember setting it back/disbale linking (or let ourselves remember by the git hook) the CI will work.
+
+#### Summary
+
+- We will always run into conflicts with the `pnpmfileChecksum` because in renovate prs it will be empty (`--ignore-pnpmfile`)
+- To keep it simple we set `--ignore-pnpmfile` in all of our CI builds to see issues immediately.
+- The only solution is to never have a `.pnpmfile.cjs` in the repository when pushing.
+  - This way there will never be a commit with `pnpmfileChecksum` in the lockfile.
+  - renovate (which uses `--ignore-pnpmfile` which we cannot disable) and other CI will work.
+- We are able to use the linking system locally if we `cp` this file from the scripts folder into `./` on demand.
+- `pnpm links:on` and `pnpm links:off` + `./scripts/setup-linking.sh` will help us with this.

+# Self-Hosting Element Call
+
+> [!NOTE]  
+> For In-App calling (Element X, Element Web, Element Desktop) use-case only
+> section [Prerequisites](#Prerequisites) is required.
+
+## Prerequisites
+
+> [!IMPORTANT]  
+> This section covers the requirements for deploying a **Matrix site**
+> compatible with MatrixRTC, the foundation of Element Call. These requirements
+> apply to both Standalone as well as Widget mode operation of Element Call.
+
+### A Matrix Homeserver
+
+The following [MSCs](https://github.com/matrix-org/matrix-spec-proposals) are
+required for Element Call to work properly:
+
+- **[MSC3266](https://github.com/deepbluev7/matrix-doc/blob/room-summaries/proposals/3266-room-summary.md):
+  Room Summary API**: In Standalone mode Element Call is able to join rooms
+  over federation using knocking. In this context MSC3266 is required as it
+  allows to request a room summary of rooms you are not joined. The summary
+  contains the room join rules. We need that information to decide if the user
+  gets prompted with the option to knock ("Request to join call"), a "cannot
+  join error" or "the join view".
+
+- **[MSC4140](https://github.com/matrix-org/matrix-spec-proposals/blob/toger5/expiring-events-keep-alive/proposals/4140-delayed-events-futures.md)
+  Delayed Events**: Delayed events are required for proper call participation
+  signalling. If disabled it is very likely that you end up with stuck calls in
+  Matrix rooms.
+
+- **[MSC4222](https://github.com/matrix-org/matrix-spec-proposals/blob/erikj/sync_v2_state_after/proposals/4222-sync-v2-state-after.md)
+  Adding `state_after` to sync v2**: Allow clients to opt-in to a change of the
+  sync v2 API that allows them to correctly track the state of the room. This is
+  required by Element Call to track room state reliably.
+
+If you're using [Synapse](https://github.com/element-hq/synapse/) as your
+homeserver, you'll need to additionally add the following config items to
+`homeserver.yaml` to comply with Element Call:
+
+```yaml
+experimental_features:
+  # MSC3266: Room summary API. Used for knocking over federation
+  msc3266_enabled: true
+  # MSC4222 needed for syncv2 state_after. This allow clients to
+  # correctly track the state of the room.
+  msc4222_enabled: true
+
+# The maximum allowed duration by which sent events can be delayed, as
+# per MSC4140.
+max_event_delay_duration: 24h
+
+rc_message:
+  # This needs to match at least e2ee key sharing frequency plus a bit of headroom
+  # Note key sharing events are bursty
+  per_second: 0.5
+  burst_count: 30
+
+rc_delayed_event_mgmt:
+  # This needs to match at least the heart-beat frequency plus a bit of headroom
+  # Currently the heart-beat is every 5 seconds which translates into a rate of 0.2Hz
+  per_second: 1
+  burst_count: 20
+```
+
+As a prerequisite for the
+[MatrixRTC Authorization Service](https://github.com/element-hq/lk-jwt-service)
+make sure that your Synapse server has either a `federation` or `openid`
+[listener configured](https://element-hq.github.io/synapse/latest/usage/configuration/config_documentation.html#listeners).
+
+### MatrixRTC Backend
+
+In order to **guarantee smooth operation** of Element Call, a MatrixRTC backend is
+required for each site deployment.
+
+![MSC4195 compatible setup](MSC4195_setup.drawio.png)
+
+As depicted above in the `example.com` site deployment, Element Call requires a
+[Livekit SFU](https://github.com/livekit/livekit) alongside a
+[MatrixRTC Authorization Service](https://github.com/element-hq/lk-jwt-service)
+to implement
+[MSC4195: MatrixRTC using LiveKit backend](https://github.com/hughns/matrix-spec-proposals/blob/hughns/matrixrtc-livekit/proposals/4195-matrixrtc-livekit.md).
+
+#### Matrix site endpoint routing
+
+In the context of MatrixRTC, we suggest using a single hostname for backend
+communication by implementing endpoint routing within a reverse proxy setup. For
+the example above, this results in:
+| Service | Endpoint | Example |
+| -------- | ------- | ------- |
+| [Livekit SFU](https://github.com/livekit/livekit) WebSocket signalling connection | `/livekit/sfu` | `matrix-rtc.example.com/livekit/sfu` |
+| [MatrixRTC Authorization Service](https://github.com/element-hq/lk-jwt-service) | `/livekit/jwt` | `matrix-rtc.example.com/livekit/jwt` |
+
+Using Nginx, you can achieve this by:
+
+```nginx configuration file
+server {
+    ...
+    location ^~ /livekit/jwt/ {
+      proxy_set_header Host $host;
+      proxy_set_header X-Real-IP $remote_addr;
+      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+      proxy_set_header X-Forwarded-Proto $scheme;
+
+      # MatrixRTC Authorization Service running at port 8080
+      proxy_pass http://localhost:8080/;
+    }
+
+    location ^~ /livekit/sfu/ {
+      proxy_set_header Host $host;
+      proxy_set_header X-Real-IP $remote_addr;
+      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+      proxy_set_header X-Forwarded-Proto $scheme;
+
+      proxy_send_timeout 120;
+      proxy_read_timeout 120;
+      proxy_buffering off;
+
+      proxy_set_header Accept-Encoding gzip;
+      proxy_set_header Upgrade $http_upgrade;
+      proxy_set_header Connection "upgrade";
+
+      # LiveKit SFU websocket connection running at port 7880
+      proxy_pass http://localhost:7880/;
+    }
+}
+```
+
+Or Using Caddy, you can achieve this by:
+
+```caddy configuration file
+# Route for lk-jwt-service with livekit/jwt prefix
+@jwt_service path /livekit/jwt/sfu/get /livekit/jwt/healthz
+handle @jwt_service {
+  uri strip_prefix /livekit/jwt
+  reverse_proxy http://[::1]:8080 {
+    header_up Host {host}
+    header_up X-Forwarded-Server {host}
+    header_up X-Real-IP {remote_host}
+    header_up X-Forwarded-For {remote_host}
+  }
+}
+
+# Default route for livekit
+handle {
+  reverse_proxy http://localhost:7880 {
+    header_up Host {host}
+    header_up X-Forwarded-Server {host}
+    header_up X-Real-IP {remote_host}
+    header_up X-Forwarded-For {remote_host}
+  }
+}
+```
+
+Using Haproxy, you can achieve this by:
+
+```
+# Frontend
+    # Match /livekit/sfu/ path
+    acl is_sfu path_beg -i /livekit/sfu/
+    use_backend sfu_backend if is_sfu matrixrtc_domain
+
+    acl is_mxrtc_auth path_beg -i /sfu/get
+    use_backend mxrtc_auth_backend if is_mxrtc_auth matrixrtc_domain
+
+# Backend
+## MatrixRTC backend
+backend sfu_backend
+    server livekit 127.0.0.1:7880
+    http-request set-path %[path,regsub(^/livekit/sfu/,/)]
+    http-request set-header Host %[req.hdr(host)]
+    timeout server 120s
+    # WebSocket support
+    option forwardfor
+    option http-server-close
+    option http-buffer-request

+backend mxrtc_auth_backend
+    server sfu 127.0.0.1:8070

+    timeout server 120s
+    # WebSocket support
+    option forwardfor
+    option http-server-close
+    option http-buffer-request
+

+
+#### MatrixRTC backend announcement
+
+> [!IMPORTANT]
+> As defined in
+> [MSC4143](https://github.com/matrix-org/matrix-spec-proposals/pull/4143),
+> the MatrixRTC backend(s) must be announced to the client via your **Matrix site's
+> `.well-known/matrix/client`** file (e.g.
+> `example.com/.well-known/matrix/client` matching the site deployment example
+> from above). The configuration is a list of Foci configs:
+
+```json
+"org.matrix.msc4143.rtc_foci": [
+    {
+        "type": "livekit",
+        "livekit_service_url": "https://matrix-rtc.example.com/livekit/jwt"
+    },
+    {
+        "type": "livekit",
+        "livekit_service_url": "https://matrix-rtc-2.example.com/livekit/jwt"
+    }
+]
+```
+
+Make sure this file is served with the correct MIME type (`application/json`).
+Additionally, ensure the appropriate CORS headers are set to allow web clients
+to access it across origins. For more details, refer to the
+[Matrix Client-Server API: 2. Web Browser Clients](https://spec.matrix.org/latest/client-server-api/#web-browser-clients).
+
+```
+Access-Control-Allow-Origin: *
+Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS
+Access-Control-Allow-Headers: X-Requested-With, Content-Type, Authorization
+```
+
+> [!NOTE]  
+> Most `org.matrix.msc4143.rtc_foci` configurations will only have one entry in
+> the array.
+
+## Building Element Call
+
+> [!NOTE]  
+> This step is only required if you want to deploy Element Call in Standalone
+> mode.
+
+Until prebuilt tarballs are available, you'll need to build Element Call from
+source. First, clone and install the package:
+
+```sh
+git clone https://github.com/element-hq/element-call.git
+cd element-call
+corepack enable
+pnpm install
+pnpm build
+```
+
+If all went well, you can now find the build output under `dist` as a series of
+static files. These can be hosted using any web server that can be configured
+with custom routes (see below).
+
+You also need to add a configuration file which goes in `public/config.json` -
+you can use the sample as a starting point:
+
+```sh
+cp config/config.sample.json public/config.json
+# edit public/config.json
+```
+
+The sample needs editing to contain the homeserver that you are using.
+
+Because Element Call uses client-side routing, your server must be able to route
+any requests to non-existing paths back to `/index.html`. For example, in Nginx
+you can achieve this with the `try_files` directive:
+
+```nginx configuration file
+server {
+    ...
+    location / {
+        ...
+        try_files $uri /$uri /index.html;
+    }
+}
+```
+
+## Configuration
+
+There are currently two different config files. `.env` holds variables that are
+used at build time, while `public/config.json` holds variables that are used at
+runtime. Documentation and default values for `public/config.json` can be found
+in [ConfigOptions.ts](../src/config/ConfigOptions.ts).
+
+> [!CAUTION]
+> Please note configuring MatrixRTC backend via `config.json` of
+> Element Call is only available for developing and debug purposes. Relying on
+> it might break Element Call going forward!
+
+## A Note on Standalone Mode of Element Call
+
+Element Call in Standalone mode requires a homeserver with registration enabled
+without any 3pid or token requirements, if you want it to be used by
+unregistered users. Furthermore, it is not recommended to use it with an
+existing homeserver where user accounts have joined normal rooms, as it may not
+be able to handle those yet and it may behave unreliably.
+
+Therefore, to use a self-hosted homeserver, this is recommended to be a new
+server where any user account created has not joined any normal rooms anywhere
+in the Matrix federated network. The homeserver used can be set up to disable
+federation, so as to prevent spam registrations (if you keep registrations open)
+and to ensure Element Call continues to work in case any user decides to log in
+to their Element Call account using the standard Element app and joins normal
+rooms that Element Call cannot handle.

-# Url Format and parameters
-
-There are two formats for Element Call urls.
-
-- **Current Format**
-
-  ```text
-  https://element_call.domain/room/#
-  /<room_name_alias>?roomId=!id:domain&password=1234&<other params see below>
-  ```
-
-  The url is split into two sections. The `https://element_call.domain/room/#`
-  contains the app and the intend that the link brings you into a specific room
-  (`https://call.element.io/#` would be the homepage). The fragment is used for
-  query parameters to make sure they never get sent to the element_call.domain
-  server. Here we have the actual matrix roomId and the password which are used
-  to connect all participants with e2ee. This allows that `<room_name_alias>` does
-  not need to be unique. Multiple meetings with the label weekly-sync can be created
-  without collisions.
-
-- **deprecated**
-
-  ```text
-  https://element_call.domain/<room_name>
-  ```
-
-  With this format the livekit alias that will be used is the `<room_name>`.
-  All ppl connecting to this url will end up in the same unencrypted room.
-  This does not scale, is super unsecure
-  (ppl could end up in the same room by accident) and it also is not really
-  possible to support encryption.
-  The url parameters are spit into two categories: **general** and **widget related**.
-
-## Widget related params
-
-**widgetId**
-The id used by the widget. The presence of this parameter implies that element
-call will not connect to a homeserver directly and instead tries to establish
-postMessage communication via the `parentUrl`.
-
-```ts
-widgetId: string | null;
-```
-
-**parentUrl**
-The url used to send widget action postMessages. This should be the domain of
-the client or the webview the widget is hosted in. (in case the widget is not
-in an Iframe but in a dedicated webview we send the postMessages same webview
-the widget lives in. Filtering is done in the widget so it ignores the messages
-it receives from itself)
-
-```ts
-parentUrl: string | null;
-```
-
-**userId**
-The user's ID (only used in matryoshka mode).
-
-```ts
-userId: string | null;
-```
-
-**deviceId**
-The device's ID (only used in matryoshka mode).
-
-```ts
-deviceId: string | null;
-```
-
-**baseUrl**
-The base URL of the homeserver to use for media lookups in matryoshka mode.
-
-```ts
-baseUrl: string | null;
-```
-
-### General url parameters
-
-**roomId**
-Anything about what room we're pointed to should be from useRoomIdentifier which
-parses the path and resolves alias with respect to the default server name, however
-roomId is an exception as we need the room ID in embedded (matroyska) mode, and not
-the room alias (or even the via params because we are not trying to join it). This
-is also not validated, where it is in useRoomIdentifier().
-
-```ts
-roomId: string | null;
-```
-
-**confineToRoom**
-Whether the app should keep the user confined to the current call/room.
-
-```ts
-confineToRoom: boolean; (default: false)
-```
-
-**appPrompt**
-Whether upon entering a room, the user should be prompted to launch the
-native mobile app. (Affects only Android and iOS.)
-
-```ts
-appPrompt: boolean; (default: true)
-```
-
-**preload**
-Whether the app should pause before joining the call until it sees an
-io.element.join widget action, allowing it to be preloaded.
-
-```ts
-preload: boolean; (default: false)
-```
-
-**hideHeader**
-Whether to hide the room header when in a call.
-
-```ts
-hideHeader: boolean; (default: false)
-```
-
-**showControls**
-Whether to show the buttons to mute, screen-share, invite, hangup are shown
-when in a call.
-
-```ts
-showControls: boolean; (default: true)
-```
-
-**hideScreensharing**
-Whether to hide the screen-sharing button.
-
-```ts
-hideScreensharing: boolean; (default: false)
-```
-
-**enableE2EE** (Deprecated)
-Whether to use end-to-end encryption. This is a legacy flag for the full mesh branch.
-It is not used on the livekit branch and has no impact there!
-
-```ts
-enableE2EE: boolean; (default: true)
-```
-
-**perParticipantE2EE**
-Whether to use per participant encryption.
-Keys will be exchanged over encrypted matrix room messages.
-
-```ts
-perParticipantE2EE: boolean; (default: false)
-```
-
-**password**
-E2EE password when using a shared secret.
-(For individual sender keys in embedded mode this is not required.)
-
-```ts
-password: string | null;
-```
-
-**displayName**
-The display name to use for auto-registration.
-
-```ts
-displayName: string | null;
-```
-
-**lang**
-The BCP 47 code of the language the app should use.
-
-```ts
-lang: string | null;
-```
-
-**fonts**
-The font/fonts which the interface should use.
-There can be multiple font url parameters: `?font=font-one&font=font-two...`
-
-```ts
-font: string;
-font: string;
-...
-```
-
-**fontScale**
-The factor by which to scale the interface's font size.
-
-```ts
-fontScale: number | null;
-```
-
-**analyticsID**
-The Posthog analytics ID. It is only available if the user has given consent for
-sharing telemetry in element web.
-
-```ts
-analyticsID: string | null;
-```
-
-**allowIceFallback**
-Whether the app is allowed to use fallback STUN servers for ICE in case the
-user's homeserver doesn't provide any.
-
-```ts
-allowIceFallback: boolean; (default: false)
-```
-
-**skipLobby**
-Setting this flag skips the lobby and brings you in the call directly.
-In the widget this can be combined with preload to pass the device settings
-with the join widget action.
-
-```ts
-skipLobby: boolean; (default: false)
-```
-
-**returnToLobby**
-Setting this flag makes element call show the lobby in widget mode after leaving
-a call.
-This is useful for video rooms.
-If set to false, the widget will show a blank page after leaving the call.
-
-```ts
-returnToLobby: boolean; (default: false)
-```
-
-**theme**
-The theme to use for element call.
-can be "light", "dark", "light-high-contrast" or "dark-high-contrast".
-If not set element call will use the dark theme.
-
-```ts
-theme: string | null;
-```
-
-**viaServers**
-This defines the homeserver that is going to be used when joining a room.
-It has to be set to a non default value for links to rooms
-that are not on the default homeserver,
-that is in use for the current user.
-
-```ts
-viaServers: string; (default: undefined)
-```
-
-**homeserver**
-This defines the homeserver that is going to be used when registering
-a new (guest) user.
-This can be user to configure a non default guest user server when
-creating a spa link.
-
-```ts
-homeserver: string; (default: undefined)
-```

+# URL Format and parameters
+
+There are two formats for Element Call URLs.
+
+## Link for sharing
+
+Requires Element Call to be deployed in [standalone](./embedded_standalone.md) mode.
+
+```text
+https://element_call.domain/room/#
+/<room_name_alias>?roomId=!id:domain&password=1234&<other params see below>
+```
+
+The URL is split into two sections. The `https://element_call.domain/room/#`
+contains the app and the intent that the link brings you into a specific room
+(`https://call.element.io/#` would be the homepage). The fragment is used for
+query parameters to make sure they never get sent to the element_call.domain
+server. Here we have the actual Matrix room ID and the password which are used
+to connect all participants with E2EE. This allows that `<room_name_alias>` does
+not need to be unique. Multiple meetings with the label weekly-sync can be created
+without collisions.
+
+Additionally the following **deprecated** format is supported:
+
+```text
+https://element_call.domain/<room_name>
+```
+
+With this format the livekit alias that will be used is the `<room_name>`.
+All people connecting to this URL will end up in the same unencrypted room.
+This does not scale, is super unsecure
+(people could end up in the same room by accident) and it also is not really
+possible to support encryption.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<https://www.gnu.org/licenses/>.
