+Routing
+----------------
+ * The default place for Acme DemoBundle routes has been changed to Acme
+   DemoBundle directory. You can find them in
+   ```Acme\DemoBundle\Resources\config\routing.yml```
+
+Command
+----------------
+ * A new demo command has been added to the AcmeDemoBundle that will help you
+   remove the bundle once you want to start working on a clean copy of
+   Symfony2 Standard. You can call it like this:
+   ```app/console demo:self-remove``` and type ```y``` when prompted to remove
+   the bundle in order to confirm the action. Else the command will display a
+   list of actions that it will do when running in ```live``` mode.
+   Make sure that the user executing the command has the needed privilages to
+   delete the files and directories mentioned while in dry-run mode.
