-## 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
-
-Please refer to the ```BUILD.md``` file under the voltha-go repo
