I suspect this question has been asked before, though all I can find are similar but distinct questions or the same one with only solutions that do not work for me.
There is a repository on GitHub that I have no control over and would like to mirror. With mirror I mean have a clone that gets updated automatically. I want this mirror to also be on GitHub. Preferably any solution would not involve much configuration or setup work from my side. However if needed I can have a script run using a cron on some VPS.
Can I create such a mirror purely via GitHub? If not, are there ready to use scripts to do this?
