'Introduction to gRPC' issue

The _Working with Protocol Buffers_ section contains this sentence:
> gRPC uses `protoc` with a special gRPC plugin to generate code from your proto file: you get generated gRPC client and server code, as well as the regular protocol buffer code for populating, serializing, and retrieving your message types. You’ll see an example of this below.

There is no example below. Perhaps it's on a different page.
