Additional context

Hey, this is generally looking great, thanks. I think what's missing to make the yarn install step happy is committing the yarn cache. If you make yarn update the package.json instead of doing it manually (see 4a93bfd), the step should work.

yarn add --dev eslint-plugin-flowtype is what you need, I think.

I added some notes on dependencies in #17.

Thanks for your suggestion. I am entirely new to the JavaScript ecosystem. But it seems it’s proper now
