Hi! That's an awesome project, thanks for your work!

I would like to contribute to a feature but I don't know how to run the tests of the project. Do you mind adding some instructions on how to setup and run the tests?

Thanks in advance

Just giving more context on what errors I'm hitting

I ran yarn and then yarn test on root and I got a bunch of TS errors:

Yeah sorry been meaning to get around to writing contributing page, just been refactoring a few things.
