 ### High-level, general-purpose asynchronous concurrency abstractions
 
-* [Actor](./doc/actor/main.md): Implements the Actor Model, where concurrent actors exchange messages. 
-* [Agent](./doc/agent.md): A single atomic value that represents an identity.
-* [Async](./doc/async.md): A mixin module that provides simple asynchronous behavior to any standard class/object or object.
-* [Future](./doc/future.md): An asynchronous operation that produces a value.
-  * [Dataflow](./doc/dataflow.md): Built on Futures, Dataflow allows you to create a task that will be scheduled when all of its data dependencies are available.
-* [Promise](./doc/promise.md): Similar to Futures, with more features. 
-* [ScheduledTask](./doc/scheduled_task.md): Like a Future scheduled for a specific future time.
