Rookie question, but how do I run linter and tests?

@GrandaddyShmax sorry but this PR is too big for the current repo and seems out of scope. Feel free to start your own fork if you want to support extra features.

Thank you, I did expect this response as this push holds too many things that are indeed irrelevant. But if there is perhaps a single feature from this toolset that you see fit, I would be more than happy to contribute it to this repository 😁
