We should look at adding files such as CONTRIBUTING.md, CODE_OF_CONDUCT.md, and FUNDING.yml, .github/ISSUE_TEMPLATE/* files, and .github/PULL_REQUEST_TEMPLATE/*.

It's pretty self-explanatory why these files would be good to have.

I'm currently looking at making PR and issue templates, (combining the good features from some already premade ones + adding some specifics for our project), but we'll need to go over them to make sure they fit our needs. I'll open a PR when I finish that.

To continue with the idea of repo maintenance, you might want to consider moving all ideas to the discussions thing. I haven't seen much use of it, but it seems to be a good concept so far.
