+Requirements
+============
+
+* a postgresql database. The minimum version is postgresql 9.1, but we are working on developing on the 9.4 branch, which will provide features which will ease developper work
+* php 5.5
+
+You won't need any web server for demonstration or development.
+
+Preparation
+===========
+
+Prepare :
+
+* your credentials to use your postgresql database
+* a random string, which will be use to improve entropy in security. Choose anything you want (random character, your father's birthplace, ...)
 
 Installation
 =============
 
 Chill is installed with composer.
 
+Install composer
+----------------
+
+..  note::
+  If you do not know composer, it is a good idea to have a glance at `the composer documentation`_ 
+
 Install composer on your system :
 
-:: 
+.. code-block:: bash
 
    curl -sS https://getcomposer.org/installer | php
 
-move composer.phar to your system.
+move composer.phar to your system (optional)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Install composer globally on you system will made the installation process more convenient. To do this, simply run 
+
+.. code-block:: bash
+   sudo mv composer.phar /usr/local/bin/composer
+
+Then, just run `composer` instead of `php composer.phar`
+
+.. note::
+   See `the composer introduction`_ to learn how to install composer on Mac OS X and Windows
+
+Create your project
+-------------------
+
+Create your Chill project using composer:
+
+.. code-block:: bash
+   php composer.phar create-project champs-libres/chill-standard path/to/your/directory --stability=dev
+
+.. note::
+   Until now, the stability of the project is set to "dev". Do not forget this argument, or composer will fail to download and create the project.
+
+Composer will download `the standard architecture`_ and ask you a few question about how to configure your project.
+
+* **database_host** : your postgresql server's address
+* **database_port** : the port to reach your postgresql server 
+* **database_name** : the name of your database
+* **database_user** : the username to reach your database
+* **database_password** : your username's password
+* **locale**: the language, as iso code. Until now, only fr is supported
+* **secret**: the secret string you prepared (see "preparation")
+
+You may accept the default parameters of **debug_toolbar**, **debug_redirects** and **use_assetic_controller** for a demonstration installation. For production, set them all to `false`.
+
+Launch your server
+-------------------
+
+If everything was fine, you are able to launch your built-in server :
+
+.. code-block::bash
+   php app/console server:run
+
+Your server should now be available at `http://localhost:8000`
