How to contribute

I have some small questions on how to contribute to this software. Is there any official way to talk to the devs (you?)? I do see some part in refactoring that I could do, but I would like to talk about it first. Honestly my Rust is a bit...rusty, but I do have several questions on some small coding decisions that I just might not get right. Would be a shame to invest my time into a PR, that just was my mistake.
