-### Project structure
+### Project Structure
 The project is structured in the following way:
 
 * **admin/**: Admin related parts which hook up the News app in the admin area. The HTML is in **templates/admin.php** folder, the JavaScript is in **js/admin/Admin.js**, CSS in **css/admin.css**. Both CSS and JavaScript don't need to be recompiled unlike everything else. The controller that hooks up the template is located in **controller/admincontroller.php**. **admin/admin.php** is just there to wire up the controllers on the admin page which does not support the App Framework.
