+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 1.4
+- 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 First [install protoc](https://github.com/google/protobuf/blob/master/README.md)
+  - For now, this needs to be installed from source
+  - This is will change once proto3 is officially released
+
+2 Install the protoc Go plugin.
+
+```
+$ go get -a github.com/golang/protobuf/protoc-gen-go
+$
+$ # from this dir; invoke protoc
+$  protoc -I ./helloworld/helloworld/ ./helloworld/helloworld/helloworld.proto --go_out=plugins=grpc:helloworld
+```
