I think the docs are out of date. Try running ./docker-build.sh instead.

Thanks for pointing it out. I updated them in #46

Also, it would be nice to have more details on how to use the protoc plugin to generate kotlin files.

I think you may not have cloned the entire repo (it has git submodules). Try doing this first: git submodule update --init --recursive. I'll add that to the instructions as well.
