 `TwigExtension` provides these functions to your Twig templates:
 
 * `url_for()` - returns the URL for a given route. e.g.: /hello/world

 You can use `url_for` to generate complete URLs to any Slim application named route and use `is_current_url` to determine if you need to mark a link as active as shown in this example Twig template:
 
-```php
-{% extends "layout.html" %}
-
-{% block body %}
+```html
 <h1>User List</h1>
 <ul>
     <li><a href="{{ url_for('profile', { 'name': 'josh' }) }}" {% if is_current_url('profile', { 'name': 'josh' }) %}class="active"{% endif %}>Josh</a></li>
     <li><a href="{{ url_for('profile', { 'name': 'andrew' }) }}">Andrew</a></li>
 </ul>
