Simplify the installation step (#345)
Simplify the installation step (#345)

The curlies in the go get argument is very unknown, I have
witnessed a few users parsing the argument to run the following
commands indiviually rather than copy/pasting the instruction:

$ go get -u github.com/golang/protobuf/protoc-gen-go
$ go get -u github.com/golang/protobuf/proto

go get the protoc-gen-go to simplify this step.
