+# How to Build the Golang based OpenOLT Adapter 
 
-# How to Build and Run a GOlang based OpenOLT Adapter 
-Assuming the VOLTHA2.0 environment is made using the quickstart.md in voltha-go.
-
-Dependencies are committed to the repos as per current standard practice.
-If you need to update them you can do so with dep. This includes the voltha-protos and voltha-go dependencies.
-
-Ensure your GOPATH variable is set according to the quickstart
-Create a symbolic link in the $GOPATH/src tree to the voltha-openolt-adapter repository:
-```sh
-mkdir -p $GOPATH/src/github.com/opencord
-ln -s ~/repos/voltha-openolt-adapter $GOPATH/src/github.com/opencord/voltha-openolt-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
 ```
 
-Install dep for fetching dependencies
-```sh
-mkdir -p $GOPATH/bin
-curl https://raw.githubusercontent.com/golang/dep/master/install.sh | sh
+## Building with a Local Copy of `voltha-protos` or `voltha-go`
+If you want to build/test using a local copy or `voltha-protos` or `voltha-go`
+this can be accomplished by using the environment variables `LOCAL_PROTOS` and
+`LOCAL_VOLTHA`. These environment variables should be set to the filesystem
+path where the local source is located, e.g.
 
-Pull and build dependencies for the project.  This may take a while.  This may likely update versions of 3rd party packages in the vendor folder.   This may introduce unexpected changes.   If everything still works feel free to check in the vendor updates as needed.
-
-cd $GOPATH/src/github.com/opencord/voltha-go/
-dep ensure
-
-If you are using a custom local copy of protos or voltha-go
-
-Just export LOCAL_PROTOS=true or LOCAL_VOLTHAGO=true to use that instead, assuming you have set them up on GOPATH. See the quickstart.
-
-mkdir -p ~/source
-cd ~/source
-git clone https://github.com/opencord/voltha-openolt-adapter.git
-cd voltha-openolt-adapter
-make build
-```
-This will create the voltha-openolt-adapter-go docker image
+```bash
+LOCAL\_PROTOS=$HOME/src/voltha-protos
+LOCAL\_VOLTHA=$HOME/src/voltha-go
 ```

-# Consul License
-
-Command: `consul license`
-
-<%= enterprise_alert :consul %>
-
-The `license` command provides datacenter-level management of the Consul Enterprise license. This was added in Consul 1.1.0.
-
-If ACLs are enabled then a token with operator privileges may be required in
-order to use this command. Requests are forwarded internally to the leader
-if required, so this can be run from any Consul node in a cluster. See the
-[ACL Guide](https://learn.hashicorp.com/consul/security-networking/production-acls) for more information.
-
-
-```text
-Usage: consul license <subcommand> [options] [args]
-
-  This command has subcommands for managing the Consul Enterprise license
-  Here are some simple examples, and more detailed examples are
-  available in the subcommands or the documentation.
-
-  Install a new license from a file:
-
-      $ consul license put @consul.license
-
-  Install a new license from stdin:
-
-      $ consul license put -
-
-  Install a new license from a string:
-
-      $ consul license put "<license blob>"
-
-  Retrieve the current license:
-
-      $ consul license get
-
-  For more examples, ask for subcommand help or view the documentation.
-
-Subcommands:

+// ConfChangeV2 messages initiate configuration changes. They support both the

+// The supplied context is treated as an opaque payload and can be used to
+// attach an action on the state machine to the application of the config change
+// proposal. Note that contrary to Joint Consensus as outlined in the Raft
+// paper[1], configuration changes become active when they are *applied* to the

+// The simple protocol can be used whenever only a single change is made.

+// Non-simple changes require the use of Joint Consensus, for which two

+// desired changes and transitions the Raft group into the joint configuration,
+// in which quorum requires a majority of both the pre-changes and post-changes
+// configuration. Joint Consensus avoids entering fragile intermediate
+// configurations that could compromise survivability. For example, without the
