Add stuff, commit stuff, push stuff. Like 99% of the time that's all you need to know how to do, especially if you're working alone.

But I think maybe part of the problem is people think it's going to be a lot more complicated than that, and who wants to learn something big and complicated when you're already trying to learn game dev, you know? At least that's my theory.

Ok I've seen the "but I use Google Drive for backups so it's fine" argument a few times from solo devs, but in a team? When you're in a hurry? Argh, nightmare fuel.
