"Getting started" documentation is incomplete

[werdnum]

My apologies if there's some more complete documentation somewhere else that I can't find.

The documentation in README is not complete. That is: it doesn't tell you everything you need to do to get an example application running. In particular, I suspect that I'm supposed to create my gRPC proto service definition somewhere for grapi to process. But I don't see that documented anywhere.

What would be helpful would be a complete walkthrough with step by step instructions of how to produce an example application. Either that, or a bit more of an explanation of the operating principle so that I can at least derive my own instructions.
