-Now install the micro fork of protoc-gen-go. The protobuf compiler for Go.

-```shell
-go get github.com/micro/protobuf/{proto,protoc-gen-go}

 ### Generate the proto
 
 After writing the proto definition we must compile it using protoc with the micro plugin.
 
 ```shell
-protoc -I$GOPATH/src --go_out=plugins=micro:$GOPATH/src \
-	$GOPATH/src/github.com/micro/examples/service/proto/greeter.proto
