 Installation
 ============
 
-Prerequisites
--------------
-PHP 5.3 and Symfony 2 are needed to make this bundle work ; there are also some
-Sonata dependencies that need to be installed and configured beforehand :
-
-    - `SonataCacheBundle <http://sonata-project.org/bundles/cache>`_
-    - `SonataBlockBundle <http://sonata-project.org/bundles/block>`_
-    - `SonatajQueryBundle <https://github.com/sonata-project/SonatajQueryBundle>`_
-    - `KnpMenuBundle <https://github.com/KnpLabs/KnpMenuBundle/blob/master/Resources/doc/index.md#installation>`_ (Version 1.1.*)
-    - `Exporter <https://github.com/sonata-project/exporter>`_
+SonataAdminBundle can be installed at any moment during a project's lifecycle,
+whether it's a clean Symfony2 installation or an existing project.
 
-You will need to install those in their 2.1 branches (or master if they don't
-have a similar branch). Also follow their configuration steps ; you will find
-everything you need in their installation chapter.
+1 - Downloading the code
+------------------------
 
-.. note::
-    If a dependency is already installed somewhere in your project or in
-    another dependency, you won't need to install it again.
+Use composer to manage your dependencies and download SonataAdminBundle:
 
-Translations
-~~~~~~~~~~~~
-If you wish to use default translation texts provided in this bundle, you have
-to make sure you have translator enabled in your config.
+.. code-block:: bash
 
-.. code-block:: yaml
+    php composer.phar require sonata-project/admin-bundle
 
-    # app/config/config.yml
-    framework:
-        translator: ~
+You'll be asked to type in a version constraint. 'dev-master' will get you the latest
+version, compatible with the latest Symfony2 version. Check `packagist <https://packagist.org/packages/sonata-project/admin-bundle>`_
+for older versions:
 
-Installation
-------------
+.. code-block:: bash
+
+    Please provide a version constraint for the sonata-project/jquery-bundle requirement: dev-master
 
-Download SonataAdminBundle and its dependencies to the ``vendor`` directory. You
-can use Composer for the automated process::
+2 - Selecting and downloading a storage bundle
+----------------------------------------------
 
-    php composer.phar require sonata-project/admin-bundle --no-update
-    php composer.phar require sonata-project/doctrine-orm-admin-bundle --no-update  # optional
-    php composer.phar require sonata-project/intl-bundle --no-update                # optional
-    php composer.phar require sonata-project/cache-bundle --no-update               # optional
-    php composer.phar update
+SonataAdminBundle is storage agnostic, meaning it can work with several storage 
+mechanism. Depending on which you are using on your project, you'll need to install
+one of the following bundles. In the respective links you'll find simple installation
+instructions for each of them:
 
-Next, be sure to enable these bundles in your AppKernel.php file:
+    - `SonataDoctrineORMAdminBundle <http://sonata-project.org/bundles/doctrine-orm-admin/master/doc/reference/installation.html>`_
+    - `SonataDoctrineMongoDBAdminBundle <https://github.com/sonata-project/SonataDoctrineMongoDBAdminBundle/blob/master/Resources/doc/reference/installation.rst>`_
+    - `SonataPropelAdminBundle <https://github.com/sonata-project/SonataPropelAdminBundle/blob/master/Resources/doc/reference/installation.rst>`_
+    - `SonataDoctrinePhpcrAdminBundle <https://github.com/sonata-project/SonataDoctrinePhpcrAdminBundle/blob/master/Resources/doc/reference/installation.rst>`_ 
+
+.. note::
+    Don't know which to choose? Most new users prefer SonataDoctrineORMAdmin, to interact with traditional relational databases (MySQL, PostrgreSQL, etc)
+    
+3 - Enabling SonataAdminBundle and its dependencies
+---------------------------------------------------
+
+SonataAdminBundle relies on other bundles to implement some features.
+Besides the storage layer mentioned on step 2, there are other bundles needed 
+for SonataAdminBundle to work:
+
+    - `SonataCacheBundle <http://sonata-project.org/bundles/cache/master/doc/reference/installation.html>`_
+    - `SonataBlockBundle <http://sonata-project.org/bundles/block/master/doc/reference/installation.html>`_
+    - `SonatajQueryBundle <https://github.com/sonata-project/SonatajQueryBundle/blob/documentation/Resources/doc/reference/installation.rst>`_
+    - `KnpMenuBundle <https://github.com/KnpLabs/KnpMenuBundle/blob/master/Resources/doc/index.md#installation>`_ (Version 1.1.*)
+
+These bundles are automatically downloaded by composer as a dependency of SonataAdminBundle.
+However, you have to enable them in your AppKernel.php, and configure them manually. Don't
+forget to enable SonataAdminBundle too:

+4 - Configuring SonataAdminBundle dependencies
+----------------------------------------------

+You will need to configure SonataAdminBundle's dependecies. For each of the above
+mentioned bundles, check their respective installation/configuration instructions
+files to see what changes you have to make to your Symfony2 configuration.

+dashboard. To be able to use it, make sure it's enabled on SonataBlockBundle's configuration:

+At this point, your Symfony2 installation should be fully functional, with no errors
+showing up from SonataAdminBundle or its dependencies. SonataAdminBundle is installed
+but not yet configured (more on that in the next section), so you won't be able to
+use it yet.
+
+If, at this point or during the installation, you come across any errors, don't panic:
+
+    -  Read the error message carefully. Try to find out exactly which bundle is causing the error. Is it SonataAdminBundle or one of the dependencies?
+    - Make sure you followed all the instructions correctly, for both SonataAdminBundle and it's dependencies
+    - Odds are that someone already had the same problem, and it's documented somewhere. Check `Google <http://www.google.com>`_, `Sonata Users Group <https://groups.google.com/group/sonata-users>`_, `Symfony2 Users Group <https://groups.google.com/group/symfony2>`_ and `Symfony Forum <forum.symfony-project.org>`_ to see if you can find a solution.
+    - Still no luck? Try checking the project's open issues on Github.

 After you have successfully installed the above bundles you need to configure
 SonataAdminBundle for administering your models. All that is needed to quickly
