Hey @lpliger I think you're having issues with the linter.
We have zero docs on that I guess, so sorry for that.

A linter is a tool that checks if your code is within the pattern we structure our code in this repo (this could be the amount of spaces between chars, or how you declare types, or even how you write your comments, etc., it's a way of stylizing the code 🙂 so we have it understandable and standardized to everyone).
Ok, so one way of running the linter tool so it standardizes your code for you is to run npm run lint if you have all the local environment built in there, another one is make lint, for now they're doing exactly the same.

If you have any questions regarding this process, feel free to ask!

Yep.
Looks great! :)
Thank you for the contribution.
