+    single: Bundle; Removing AcmeDemoBundle
+
+How to remove the AcmeDemoBundle
+================================
+
+The Symfony2 Standard Edition comes with a complete demo, that lives inside a
+bundle called ``AcmeDemoBundle``. It is a great boilerplate to refer to while
+starting with your project, but later on the project, it will become usefull
+to remove this bundle.
+
+.. tip::
+
+    This article uses the AcmeDemoBundle as an example, you can use this
+    article on every bundle you want to remove.
+
+1. Unregister the bundle in the ``AppKernel``
+---------------------------------------------
+
+To disconnect the bundle from the framework, you should remove the bundle from
+the ``Appkernel::registerBundles()`` method. The bundle is normally found in
+the ``$bundles`` array but the ``AcmeDemoBundle`` is only registered in a
+development environment and you can find him in the if statement thereafter::
+
+    // app/AppKernel.php
+
+    // ...
+    class AppKernel extends Kernel
+    {
+        public function registerBundles()
+        {
+            $bundles = array(...);
+
+            if (in_array($this->getEnvironment(), array('dev', 'test'))) {
+                // comment or remove this line:
+                // $bundles[] = new Acme\DemoBundle\AcmeDemoBundle();
+                // ...
+            }
+        }
+    }
+
+2. Remove bundle configuration
+------------------------------
+
+Now Symfony doesn't know about the bundle, you need to remove any
+configuration and routing configuration inside the ``app/config`` directory
+that refers to the bundle.
+
+2.1 Remove bundle routing
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The routing for the AcmeDemoBundle can be found in
+``app/config/routing_dev.yml``. The routes are ``_welcome``, ``_demo_secured``
+and ``_demo``.
+
+2.2 Remove bundle configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Some bundles contains configuration in one of the ``app/config/config*.yml``
+files. Be sure to remove the related configuration from these files. You can
+quickly spot bundle configuration by looking at a ``acme_demo`` (or whatever
+the name of the bundle is, e.g. ``fos_user`` with the FOSUserBundle) string in
+the configuration files.
+
+The AcmeDemoBundle doesn't have configuration. However, the bundle has set up
+the ``app/config/security.yml`` file. You can use it as a boilerplate for your
+own security, but you **can** also remove everything: It doesn't make sense to
+Symfony if you remove it or not.
+
+3. Remove integration in other bundles
+--------------------------------------
+
+Some bundles rely on other bundles, if you remove one of the two, the other
+will properbly not work. Be sure that no other bundles, third party or self
+made, relies on the bundle you are about to remove.
+
+.. tip::
+
+    If a bundle relies on another bundle, it means in most of the cases that
+    it uses some services from the other bundle. Searching for a ``acme_demo``
+    string will help you spot them.
+
+.. tip::
+
+    If a third party bundle relies on another bundle, you can find the bundle
+    in the ``composer.json`` file included in the bundle directory.
+
+4. Remove the bundle from the filesystem
+----------------------------------------
+
+Now you have removed every reference to the bundle in the Symfony2
+application, the last thing you should do is removing the bundle from the file
+system. The bundle is located in the ``src/Acme/DemoBundle`` directory. You
+should remove this directory and you can remove the ``Acme`` directory as
+well, you likely won't get other bundles in that vendor.
+
+.. tip::
+
+    If you don't know the location of a bundle, you can use the
+    :method:`Symfony\\Bundle\\FrameworkBundle\\Bundle\\Bundle::getPath` method
+    to get the path of the bundle::
+
+        echo $this->container->get('kernel')->getBundle('AcmeDemoBundle')->getPath();
