How do I edit the wiki?

[RealNath]

I'd like to add more information to the wiki since it's missing a lot of stuff. It said that everyone is welcome to edit the wiki, but I can't seem to find the option to edit it. I tried to clone the wiki (FModel.wiki.git), then push the edit but it said I don't have access. I thought I'm supposed to make a fork and create a PR, but the repo seems to be a fork of the FModel repo but with only a bunch of MD files and nothing else, which I thought isn't supposed to be how it works since this repo doesn't have the wiki markdown files themselves.
