I used to do this, looks like I need to reinstall, so would like to do this again.
But for the life of me I cannot remember what I used! Any recommendations?

Do you mean “creating a bare git repo and pushing your configs to Github/Gitlab/bitbucket” ?

Doh, found it - yadm!! I was searching with keyword config, changed to dotfiles and found it straight away!
