+## Relationship between Operations, Consumers, and Producers
+
+Operations in AsyncAPI are closely related to the high-level concepts of Consumers and Producers. A Producer is an application that sends messages, while a Consumer is an application that receives messages. In the context of AsyncAPI operations:
+- An operation with the `action` set to `send` corresponds to a Producer.
+- An operation with the `action` set to `receive` corresponds to a Consumer.
+
+Understanding this relationship helps in designing and documenting the interactions between different components in an event-driven architecture. For more details on Consumers and Producers, refer to the [Consumer](/docs/concepts/consumer) and [Producer](/docs/concepts/producer) pages.
