 ## GENERAL
 
 ### Description
-The C++ messaging library can be used to send and receive QPID messages in C++ code.  The Python code provides a template for mini services that communicate by RPCs.
+This module contains code for the C++ library `libmessaging.so` and a base class for Python mini services.  The C++ library can send and receive QPID messages while the Python base class communication is done through RPCs.

 ### Overview
-*TODO*
+The Python class `AbstractBusListener` is the base class for Python services that are listening on the QPID bus for a certani type of message.  The following Python services inherit from `AbstractBusListener`:
+
+- `Service`:  This is the base class for RPC micro services.
+- `TriggerNotificationListener`
+- `OTDBBusListener`
+- `IngestBusListener`
+- `DataManagementBusListener`
+- `RABusListener`
