   $ go install github.com/golang/protobuf/protoc-gen-go@latest
   $ # Run the following if you haven't done so already.
   $ export PATH="$PATH:$(go env GOPATH)/bin"
   

2. Generate code from the protobuf definition file.

   $ mkdir hello
   $ protoc -I . hello.proto --go_out=plugins=grpc:$(PROTO_DIR) \
     --go_opt=paths=source_relative
   

3. Run both server and client concurrently.
