Customizing the web UI
######################
-There is currently no pluggable way of customizing the web UI apart from the settings available in
-:ref:`swagger-ui-settings` and :ref:`redoc-ui-settings`. If you really need to, you can override one of the
-``drf-yasg/swagger-ui.html`` or ``drf-yasg/redoc.html`` templates that are used for rendering.
+The web UI can be customized using the settings available in :ref:`swagger-ui-settings` and :ref:`redoc-ui-settings`.
+
+You can also extend one of the ``drf-yasg/swagger-ui.html`` or ``drf-yasg/redoc.html`` templates that are used for
+rendering. The customizable blocks are currently limited to:
+
+{% block extra_styles %}
+ additional stylesheets
+
+{% block extra_scripts %}
+ additional scripts
+
+{% block user_context_message %}
+ *(swagger-ui session auth only)*
+ logged in user message
