Add a basics tutorial to show how to use this crate

[BusyJay]

Although there are examples and tests already, it would be better to have a tutorial just like https://grpc.io/docs/ lists.

Yes, we should add it ASAP.

Hi has there been any progress on this? My main issue is that it seems like the proto generated files assume a particular dir structure and therefore maybe a module like cargo build.

Not sure how to set up my project to use this.

[BusyJay]

The structure it assumes is the same as rust-protobuf does. You need to add a mod.rs manually to include all the generated codes.

In learning how to use the crate I created a small sample project reusing the components of this repo. https://github.com/toidiu/grcp-rs-example

I would appreciate any feedback you might have.

Unless someone is already working on this issue, I'd like to run with it. I tend to prefer the mdBook style over other documentation methods like github wikis or just markdown files in the repo. Using mdbook would require some additional consideration for hosting/infrastructure though. I'd like to get some input from others before committing to a particular documentation format/system. Until then, I'll work on general guides and examples.

No, IIRC there's nobody working on this currently.
We'll appreciate your contribution.
