     Twig can also do things that PHP can't, such as true template inheritance
     (Twig templates compile down to PHP classes that inherit from each other),
     whitespace control, sandboxing, and the inclusion of custom functions
     and filters that only affect templates. Twig contains little features
     that make writing templates easier and more concise. Take the following
     example, which combines a loop with a logical ``if`` statement:

+Asyncronous Content with hinclude.js
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. versionadded:: 2.1
+    hinclude.js support was added in Symfony 2.1
+
+Controllers can be embedded asyncronous using the hinclude.js_ javascript library.
+As the embedded content comes from another page (or controller for that matter),
+Symfony2 uses the standard ``render`` helper to configure ``hinclude`` tags:
+
+.. configuration-block::
+
+    .. code-block:: jinja
+
+        {% render '...:news' with {}, {'standalone': 'js'} %}
+
+    .. code-block:: php
+
+        <?php echo $view['actions']->render('...:news', array(), array('standalone' => 'js')) ?>
+
+.. note::
+
+   hinclude.js_ needs to be included in your page to work.
+
+Default content (while loading or if javascript is disabled) can be set globally
+in your application configuration:
+
+.. configuration-block::
+
+    .. code-block:: yaml
+
+        # app/config/config.yml
