+=========================
+Misago Context Processors
+=========================
+
+Context Processors are simple python functions that receive HttpRequest object and extend template context with additional values. In addition to `default context processors defined by Django <https://docs.djangoproject.com/en/dev/ref/templates/api/#subclassing-context-requestcontext>`_, Misago defines its own context processors:
+
+
+misago.core.context_processors.site_address
+===========================================
+
+:py:func:`misago.core.context_processors.site_address`
+
+This function adds `SITE_ADDRESS` value to template context that you can use to build absolue links in your templates::
+
+    # Will become "http://mysite.com/"
+    {{ SITE_ADDRESS }}{% url 'forum_index' %}
+
+This is most useful for links in e-mail templates.
