+In-line Code Annotations for An Open edX Event
+==============================================
+
+When creating a new Open edX Event, you must document the event definition using in-line code annotations. These annotations provide a structured way to document the event's metadata, making it easier for developers to understand the event's purpose and how it should be used.
