not really familiar with github. i created a repository with the mod files and linked it as "source" on here. ill have a closer look on how to properly set up a mod on github the next few days
if you don't have skill or time i can make a repo for you with basic settings and give you the right.
in addition i recommand to use gitkraken for issue/pr managment or vscode+gitlens (more ugly but more versatil)
the interface of web version of github it's not really user-friendly :/
