+gRPC in 3 minutes (Go)
+======================
+
+BACKGROUND
+-------------
+For this sample, we've already generated the server and client stubs from [helloworld.proto](helloworld/helloworld/helloworld.proto).
+
+PREREQUISITES
+-------------
+
+- This requires Go 1.6 or later
+- Requires that [GOPATH is set](https://golang.org/doc/code.html#GOPATH)
+
+```
+$ go help gopath
+$ # ensure the PATH contains $GOPATH/bin
+$ export PATH=$PATH:$GOPATH/bin
+```
+
+INSTALL
+-------
+
+```
+$ go get -u google.golang.org/grpc/examples/helloworld/greeter_client
+$ go get -u google.golang.org/grpc/examples/helloworld/greeter_server
+```
+
+TRY IT!
+-------
+
+- Run the server
+
+  ```
+  $ greeter_server &
+  ```
+
+- Run the client
+
+  ```
+  $ greeter_client
+  ```
+
+OPTIONAL - Rebuilding the generated code
+----------------------------------------
+
+1. Install [protobuf compiler](https://github.com/google/protobuf/blob/master/README.md#protocol-compiler-installation)
+
+1. Install the protoc Go plugin
+
+   ```
+   $ go get -u github.com/golang/protobuf/protoc-gen-go
+   ```
+
+1. Rebuild the generated Go code
+
+   ```
+   $ go generate google.golang.org/grpc/examples/helloworld/...
+   ```
+   
+   Or run `protoc` command (with the grpc plugin)
+   
+   ```
+   $ protoc -I helloworld/ helloworld/helloworld.proto --go_out=plugins=grpc:helloworld
+   ```
