 Now that you've read about [the workflow building block]({{< ref workflow-overview >}}) and created your worfklow component, learn more about how to:
 
 - Use the built-in worfklow component
-- Register an external workflow engine with Dapr.

-Currently, Dapr supports two external workflow engines:
-- Temporal.io
-- Logic Apps
+## Built-in workflow vs external workflows
+
+When you run `dapr init`, Dapr creates a default built-in workflow component. This component is written in Go and implements workflow instances as actors to promote placement and scalability.

+You can write your Temporal.io or Logic Apps worfklow instances and register them with the Dapr sidecar with all the features of the Dapr workflow API.
