 The Dapr Workflow engine is internally implemented using then open source [durabletask-go](https://github.com/microsoft/durabletask-go) library, which is embedded directly into the Dapr sidecar. Dapr implements a custom durable task "backend" using internally managed actors, which manage workflow scale-out, persistence, and leader election. This article will go into more details in subsequent sections.

 ## Sidecar interactions
 
 TODO: Describe the gRPC protocol used in the SDK/sidecar interactions. Make sure to also emphasize the responsibilities of the app vs. the responsibilities of the sidecar.

 Essentially, to use the Dapr Workflow building block, you write workflow code in your application using the SDK and connect to the sidecar using gRPC stream. This will register the workflow and any workflow activities, or tasks that workflows can schedule.
