+How to render a template without a custom controller
+====================================================
+
+This guide explains how to render a template within another template and
+how to configure a page without a custom controller.
+
+The intention is, that there may be page in your application, that doesn't
+need a controller, because there is no action associated with them.
+
+Rendering a template in twig:
+
+.. code-block:: jinja
+
+    {% render "FrameworkBundle:Template:template" with {template: 'AcmeBundle::static.html.twig'} %}
+
+Directly routing to a template without custom controller with additional
+caching parameters:
+
+.. configuration-block::
+
+    .. code-block:: yaml
+
+        acme_static:
+            pattern: /static
+            defaults:
+                _controller: FrameworkBundle:Template:template
+                template: 'AcmeBundle::static.html.twig'
+                maxAge: 86400
+                sharedMaxAge: 86400
+
+    .. code-block:: xml
+
+        <?xml version="1.0" encoding="UTF-8" ?>
+
+        <routes xmlns="http://symfony.com/schema/routing"
+            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+            xsi:schemaLocation="http://symfony.com/schema/routing http://symfony.com/schema/routing/routing-1.0.xsd">
+
+            <route id="acme_static" pattern="/static">
+                <default key="_controller">FrameworkBundle:Template:template</default>
+                <default key="template">AcmeBundle::static.html.twig</default>
+                <default key="maxAge">86400</default>
+                <default key="sharedMaxAge">86400</default>
+            </route>
+        </routes>
+
+    .. code-block:: php
+
+        use Symfony\Component\Routing\RouteCollection;
+        use Symfony\Component\Routing\Route;
+
+        $collection = new RouteCollection();
+        $collection->add('acme_static', new Route('/static', array(
+            '_controller'  => 'FrameworkBundle:Template:template',
+            'template'     => 'Acmebundle::static.html.twig',
+            'maxAge'       => 86400,
+            'sharedMaxAge' => 86400,
+        )));
+
+        return $collection;
+
+By default no caching headers were set. If you want to disable proxy
+caching, but want to keep browser caching enabled, set ``private`` to
+``false`` explictly.
