 Send a rpc to a helloworld server at `localhost:50051`:

 The `localhost:50051` part indicates the server you are connecting to. `SayHello` is (part of) the
-gRPC method string. Then there is the path to the proto file containing the service definition,

+### Use local proto files
+
+If the server does not have the server reflection service, you will need to provide local proto
