I don't really feel like Facebook or Google are good fits for me, and typically use GitHub as the account creation/login of choice whenever it is available.

If you don't mind, I'd like to take this one. It'll be a good first issue for me on the codebase itself, and will help make sure I have my dev environment setup correctly.

Probably will take a week or so to get to it though.

Sure thing. Let me know if you need any help. I'll be available on Discord as well.

This made me realize there isn't any information for would-be contributors on how to get started. So naturally, i opened #17 🤣
