# Greeter This is the simplest grpc example, which does not reference any external grpc libraries. The following plug-ins are used: * [protoc-gen-go](https://google.golang.org/protobuf/cmd/protoc-gen-go) * [protoc-gen-go-grpc](https://google.golang.org/grpc/cmd/protoc-gen-go-grpc) You can compile the proto file in this directory by executing the following command: ``` powerproto build -r ./apis ``` Not surprisingly, you will get the following output: ``` ➜ tree . ├── README.md ├── apis │   ├── greeter.pb.go │   ├── greeter.proto │   └── greeter_grpc.pb.go └── powerproto.yaml 1 directory, 5 files ```
