+Hello World tutorial
+====================
+
+The purpose of this tutorial is to explain how to add our SDK as a dependency of an Java project and how to create the `Core` object that all our APIs depends on.
+
+Start by taking a look at the `build.gradle` file to see how we reference the Linphone SDK and add it as a dependency of our project.
+
+The user interface will only display the `Core`'s version, but in the next tutorial you will learn how to use it to login your SIP account.

+Account login tutorial
+====================
+
+Now that you have set up Linphone-SDK in a Java project, let's start using it.
+
+We will see how to login on a SIP server using the `Core` object instanciated in the previous tutorial.
+
+If you don't have a SIP server yet, you can create an account for free using our [free SIP service](https://subscribe.linphone.org/).
+
+Once you'll be logged-in, you'll be able to continue to the next tutorials to make calls.

+Incoming call tutorial
+====================
+
+This tutorial will focus on how the app will be notified when a call is being received and how to either accept it or terminate it.
+
+We'll also cover how to toggle the microphone and the speakerphone during an active call.
+
+If you want to test it on either a device, you'll need another SIP client to make the call. If you don't, you can use the [outgoing call tutorial](https://gitlab.linphone.org/BC/public/tutorials/-/tree/master/java/4-OutgoingCall) to do it.

+#
+#   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/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

+#
+#   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/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

+Java tutorials
+====================
+
+Tutorials are numbered 0 to 3, and we recommend you to read them in that order as features from previous tutorials are used in the next ones, such as account login.
+
+Each tutorial is a full project, so you should build it and run it independently.
+For each tutorial, you need to extract the Linphone Java SDK zip file in the tutorial directory and run `./gradlew run` to execute it.
+
+Code is being kept as short and simple as possible, and comments explain how and why things are being done.
+
+Full Java API is available [here](http://linphone.org/snapshots/docs/liblinphone/latest/java).

-# Hello World tutorial
-
-The purpose of this tutorial is to explain how to build a Qt app depending on the Linphone SDK and to create the `Core` object that all our APIs depends on.
-
-The user interface will only display the `Core`'s version, but in the next tutorial you will learn how to use it to login your SIP account.
-
-
-## How to build
-
-In the following instructions, replace **<PATH-TO-SDK>** by the real path where your SDK is located, e.g. *~/projects/linphone-sdk/build-default/linphone-sdk/desktop/*
-
-    mkdir build
-    cd build

-# Incoming call tutorial
-
-This time we are going to receive our first calls!
-
-If you don't have SIP friends to test with, you can also install Linphone on your mobile device (Android or iOS) and call yourself with a different account.
-
-
-## How to build
-
-In the following instructions, replace **<PATH-TO-SDK>** by the real path where your SDK is located, e.g. *~/projects/linphone-sdk/build-default/linphone-sdk/desktop/*
-
-    mkdir build
-    cd build
-    cmake .. -DCMAKE_PREFIX_PATH=<PATH-TO-SDK>
-    cmake --build .
