+``filter``
+==========
+
+Filter sections allow you to apply regular Twig filters on a block of template
+data. Just wrap the code in the special ``filter`` section:
+
+.. code-block:: jinja
+
+ {% filter upper %}
+ This text becomes uppercase
+ {% endfilter %}
+
+You can also chain filters:
+
+.. code-block:: jinja
+
+ {% filter lower|escape %}
+ <strong>SOME TEXT</strong>
+ {% endfilter %}
+
+ {# outputs "<strong>some text</strong>" #}
