+
+### Building Simulated OLT and ONU Adapters
+Simulated OLT, ONU and rw_core can be build together:
+```
+make build
+```
+or they via be individually built:
+```
+make rw_core
+make simulated_olt
+make simulated_onu
+```
+
+### Running rw_core, Simulated OLT and ONU Adapters
+In the example below we are using the docker-compose command to run these containers locally.
+```
+DOCKER_HOST_IP=<Host IP> docker-compose -f compose/docker-compose-zk-kafka-test.yml up -d
+DOCKER_HOST_IP=<Host IP> docker-compose -f compose/docker-compose-etcd.yml up -d

+## How to Build and Run a Voltha Go language Adapter
+
+This directory is a repo for all voltha adapters written in Go language.  At this time, the simulated_olt and 
+simulated_onu adapters are the only adapters using the Go language.  These adapters provide basic capabilities
+which will be used for high availability and capacity testing.

+### Building and running the Simulated OLT and ONU Adapters
