+Installing the Symfony Demo application
+---------------------------------------
+
+The Symfony Demo application is a fully-functional application that shows in
+practice the recommended way to develop Symfony applications. The application
+has been conceived as a learning tool for Symfony newcomers and its source code
+contains tons of comments and helpful notes.
+
+In order to download the Symfony Demo application, execute the ``demo`` command
+of the Symfony Installer anywhere in your system:
+
+.. code-block:: bash
+
+    # Linux, Mac OS X
+    $ symfony demo
+
+    # Windows
+    c:\projects\> php symfony demo
+
+Once downloaded, enter into the ``symfony_demo/`` directory and run the PHP's
+built-in web server executing the ``php app/console server:run`` command. Access
+to the ``http://localhost:8000`` URL in your browser to start using the Symfony
+Demo application.
