I'm suprised anyone found this and is possibly interesting in contributing, but if you are, here are some guidelines.
Please fork the repo, make your changes, and make a pull request. I'll review the pull request and merge it with the main repo if appropriate. If isn't merged, I'll provide feedback as to why.

Not much more than that at the moment. Thank you!
