+CartoDB User Table
+==================
+
+Introduction
+----------
+A CartoDB user table is a table with a well-known set of columns and a well-known set of triggers attached on.
+
+Columns
+----------
+The required columns of a CartoDB table are:
+
+-  ``cartodb_id``
+  - This column will be used as the primary key of the table and it has a sequence as default value
+  - Its values must be integer, non-zero, non-null and unique
+  -  B-Tree indexed
+-  ``the_geom``
+  - This column stores the main geometric features of a table
+  - The type of the column in the Postgres database is ``geometry(Geometry,4326)```
+  - GiST indexed
+  -  geometry, GiST indexed, constrained (see below)
+-  ``the_geom_webmercator``
+  - This column stores the geometries used for rendering purposes
+  - The type of the column in the Postgres database is ``geometry(Geometry,3857)``
+  - GiST indexed
+  - This column is automatically updated by the system when the ``the_geom`` column is updated or when there is an insertion of a new row into the table (See triggers below)
+
+The values of ``the_geom`` and ``the_geom_webmercator`` must be two-dimensional Points, MultiLineStrings or MultiPolygons. Different geometric types in a CartoDB table are not supported.
+
+Described table example
+^^^^^^^^^^
+::
+
+        Column        |          Type           |                       Modifiers                        
+  ----------------------+-------------------------+--------------------------------------------------------
+   cartodb_id           | bigint                  | not null default nextval('t_cartodb_id_seq'::regclass)
+   the_geom             | geometry(Geometry,4326) | 
+   the_geom_webmercator | geometry(Geometry,3857) | 
+  Indexes:
+      "table_name_pkey" PRIMARY KEY, btree (cartodb_id)
+      "table_name_the_geom_idx" gist (the_geom)
+      "table_name_the_geom_webmercator_idx" gist (the_geom_webmercator)
+
+Triggers
+----------
+The triggers generated in each CartoDB table are:
+
+-  ``track_updates`` after modifying statement updates ``cdb_tablemetadata``
+-  ``test_quota`` before changing statement to forbid if overquota
+-  ``test_quota_per_row`` before insert ot update row to forbid if overquota (checked on a probabilistic basis)
+-  ``update_the_geom_webmercator`` before insert or update row to maintain the ``the_geom_webmercator`` updated with the contents in ``the_geom``
+
+Described triggers example
+^^^^^^^^^^
+::
+
+  test_quota BEFORE INSERT OR UPDATE ON t FOR EACH STATEMENT EXECUTE PROCEDURE cdb_checkquota('0.1', '-1', 'public')
+  test_quota_per_row BEFORE INSERT OR UPDATE ON t FOR EACH ROW EXECUTE PROCEDURE cdb_checkquota('0.001', '-1', 'public')
+  track_updates AFTER INSERT OR DELETE OR UPDATE OR TRUNCATE ON t FOR EACH STATEMENT EXECUTE PROCEDURE cdb_tablemetadata_trigger()
+  update_the_geom_webmercator_trigger BEFORE INSERT OR UPDATE OF the_geom ON t FOR EACH ROW EXECUTE PROCEDURE _cdb_update_the_geom_webmercator()
+
+
+Further details
+----------
+
+Some conversions will be attempted to perform upon cartodbfication when certain fields appear:
+
+-  ``cartodb_id``: If found type TEXT will be attempted to cast to integer. If not casteable, an eror will be raised.
+-  ``the_geom``: If found type TEXT will be attempted to cast to geometry(Geometry,4326).

 - ...ease modifications and increase quality of the code
 
 
+What is the CartoDBfycation
+---------------------------
 
-What is the cartodbfycation
-===========================
-
-The cartodbfycation is the process of converting an arbitrary postgres table into a valid CartoDB table, and register it in the system so that it can be used in the CartoDB editor and platform to generate maps and analysis.
-
+The CartoDBfycation is the process of converting an arbitrary postgres table into a valid CartoDB table, and register it in the system so that it can be used in the CartoDB editor and platform to generate maps and analysis.
 
+It is performed by running the function ``CDB_CartodbfyTable(reloid REGCLASS)`` over a target table.
 
 Valid CartoDB tables
-====================
+--------------------
 
 A valid CartoDB table shall meet the following conditions:
 
-- Have a ``cartodb_id`` integer column as primary key with a sequence as default value
+- Have a ``cartodb_id`` column with integer, unique, non-zero and non-null values as primary key with a sequence as default value
 - Have a ``the_geom`` column of type ``Geometry`` with SRID 4326
 - Have a ``the_geom_webmercator`` column of type ``Geometry`` with SRID 3857
-- The columns ``the_geom`` and ``the_geom_webmercator`` shall be in sync
+- The columns ``the_geom`` and ``the_geom_webmercator`` shall be in sync (task of the ``update_the_geom_webmercator`` trigger)
 
 Additionally, a CartoDB table can contain other columns.
 
+See the `CartoDB User Table documentation`_
 
+.. _CartoDB User Table documentation: https://github.com/CartoDB/cartodb-postgresql/blob/master/doc/CartoDB-user-table.md 
+for further information.
 
 High level requirements
-=======================
+-----------------------
 
 Here is a list of high level requirments for the public function ``CDB_CartodbfyTable()``:
 
-- A call to ``CDB_CartodbfyTable()`` shall modify/rewrite the table and produce a valid CartoDB table with the same name.
-- A call to ``CDB_CartodbfyTable()`` shall cause the registration of the table into the platform
-- It shall be idempotent, meaning that successive calls to ``CDB_CartodbfyTable()`` shall not produce any visible effect in the system.
+- A call to the function shall modify/rewrite the table and produce a valid CartoDB table with the same name.
+- A call to the function shall cause the registration of the table into the platform.
+- It shall be idempotent, meaning that successive calls to the function shall not produce any visible effect in the system.
 - If there's a column containing a geometry, it shall be used to generate ``the_geom`` and the ``the_geom_webmercator`` columns.
 - Exporting and re-importing the same table in CartoDB shall produce equivalent tables, with the same features associated to the same ``cartodb_id``'s.
 
-Note that there should be only one feature per row in the source table. If there's more than one, then which one is used for ``the_geom`` and ``the_geom_webmercator`` fields is not determined.
 
+Note that there should be only one geometry per row in the source table. If there's more than one, then which one is used for ``the_geom`` and ``the_geom_webmercator`` fields is not determined.
 
 
 Low-level requirements
-======================
+----------------------
 
-- If the original table contains a valid (unique and not null) ``cartodb_id`` column, it shall be used
-- If the original table contains a ``the_geom`` column or a ``the_geom_webmercator`` column in the expected projection (EPSG 4326 and EPSG 3857, respectively) they shall be used.
+- If the original table contains a valid (integer, unique, non-zero and not null) ``cartodb_id`` column, it shall be used
+- If the original table contains a ``the_geom`` column or a ``the_geom_webmercator`` geometric column in the expected projection (EPSG 4326 and EPSG 3857, respectively) they shall be used.
 - A modification of a cartodbfy'ed table shall insert or update a row in ``CDB_TableMetadata``
 - A cartodbfy'ed table shall have a ``btree`` index on ``cartodb_id``
 - A cartodbfy'ed table shall have ``gist`` indices on ``the_geom`` and ``the_geom_webmercator``
-- Cartodbfy shall deal with text columns for imports, regarding CartoDB columns
-
+- Cartodbfy shall deal with text columns for imports, regarding CartoDB columns (``cartodb_id``, ``the_geom``, ``the_geom_webmercator``)
