-    Subclasses should implement the `process_event` method to define their specific event handling behavior.
+    Firstly, we would create a consumer class extending from CoreEventConsumerBase
+    and decide how to process the incoming events by defining the process_event.
+    Then, we would specify the type of event we want to receive by registering with the Notifier.
+    After that, we create an object of the consumer class by providing
+    the registration_id and registered_queue and start consuming the event.
