+************************************
+Configuration for Non-HTML Responses
+************************************
+
+By default, Django-Meta is designed to work with HTML responses.
+
+However, it can also be configured to work with non-HTML responses, such as JSON or XML.
+
+To do this, you can define your own meta classes and register them with the django-meta app.
