+## Installation using Git and Composer
+
+You must have [Composer] installed and ready to download the Sonerezh's
+dependencies. You will also need PHP (obviously) and at least ``php-mysql`` or
+``php-pgsql`` and ``php-gd``.
+
+1. Download the sources:
+
+    ```sh
+    $ git clone https://github.com/Sonerezh/sonerezh.git
+    ```
+
+2. Download the dependencies:
+
+    ```sh
+    $ cd sonerezh
+    $ composer install
+    ```
+
+3. You should be good to run Sonerezh using:
+
+    ```sh
+    $ cd app/webroot
+    $ CAKEPHP_DEBUG=1 php -S localhost:8080
+    ```
+
+_Note: you may have some issues to display the cover arts using the built-in PHP
+server._
