 ### Requirements
-* needs the latest Dockernet to be installed in the system
- * the wrapper uses standard Python imports to use the Dockernet modules
-* Uses ZeroMQ based RPC to open a cloud-like interface that can be used by a demo CLI client
- * pip install import zerorpc
- * This will be replaced / extended by a REST API later
+* needs the latest [Dockernet](https://github.com/mpeuster/dockernet) to be installed on the system
+ * the emulator is implemented against Dockernet's APIs
