 Add a Touch of Symfony2
 ~~~~~~~~~~~~~~~~~~~~~~~
 
-Symfony2 to the rescue. Before actually using Symfony2, you need to make
-sure PHP knows how to find the Symfony2 classes. This is accomplished via
-an autoloader that Symfony provides. An autoloader is a tool that makes it

+Symfony2 to the rescue. Before actually using Symfony2, you need to download
+it. This can be done by using Composer, which takes care of downloading the
+correct version and all its dependencies and provides an autoloader. An 
+autoloader is a tool that makes it possible to start using PHP classes 
+without explicitly including the file containing the class.
 
-First, `download Symfony`_ and place it into a ``vendor/symfony/symfony/`` directory.
-Next, create an ``app/bootstrap.php`` file. Use it to ``require`` the two
-files in the application and to configure the autoloader:
+In your root directory, create a ``composer.json`` file with the following
+content:
 
-.. code-block:: html+php
+.. code-block:: json
 
-    <?php
-    // bootstrap.php
-    require_once 'model.php';
-    require_once 'controllers.php';
-    require_once 'vendor/symfony/symfony/src/Symfony/Component/ClassLoader/UniversalClassLoader.php';
+    {
+        "require": {
+            "symfony/symfony": "2.1.*"
+        },
+        "autoload": {
+            "files": ["model.php","controller.php"]
+        }
+    }
+    
+Next, `download Composer`_ and then run the following command, which will download Symfony
+into a vendor/ directory:
 
-    $loader = new Symfony\Component\ClassLoader\UniversalClassLoader();
-    $loader->registerNamespaces(array(
-        'Symfony' => __DIR__.'/../vendor/symfony/symfony/src',
-    ));
+.. code-block:: bash
 
-    $loader->register();
+    $ php composer.phar install
 
-This tells the autoloader where the ``Symfony`` classes are. With this, you
-can start using Symfony classes without using the ``require`` statement for
-the files that contain them.
+Beside downloading your dependencies, Composer generates a ``vendor/autoload.php`` file,
+which takes care of autoloading for all the files in the Symfony Framework as well as 
+the files mentioned in the autoload section of your `composer.json`.
 
 Core to Symfony's philosophy is the idea that an application's main job is
 to interpret each request and return a response. To this end, Symfony2 provides
