+# How to Build the Golang based Simulated OLT Adapter
+
+## Working with Go Dependencies
+This project uses Go Modules https://github.com/golang/go/wiki/Modules to manage
+dependencies. As a local best pratice this project also vendors the dependencies.
+If you need to update dependencies please follow the Go Modules best practices
+and also perform the following steps before committing a patch:
+```bash
+go mod tidy
+go mod verify
+go mod vendor
+```
+
+## Building with a Local Copy of `voltha-protos` or `voltha-lib-go`
+If you want to build/test using a local copy or `voltha-protos` or `voltha-lib-go`
+this can be accomplished by using the environment variables `LOCAL_PROTOS` and
+`LOCAL_LIB_GO`. These environment variables should be set to the filesystem
+path where the local source is located, e.g.
+
+```bash
+LOCAL\_PROTOS=$HOME/src/voltha-protos
+LOCAL\_LIB\_GO=$HOME/src/voltha-lib-go
+```
+
+When these environment variables are set the vendored versions of these packages
+will be removed from the `vendor` directory and replaced by coping the files from
+the specified locations to the `vendor` directory. *NOTE:* _this means that
+the files in the `vendor` directory are no longer what is in the `git` repository
+and it will take manual `git` intervention to put the original files back._
