Dr. Mowinckel's blog: I formatted my Mac last year and was so thankful my colleague Inge had helped me setup a dotfiles repo years ago. If you're not familiar with the concept: dotfiles(https://driesvints.com/blog/getting-started-with-dotfiles/) are the hidden configuration files that live in your home directory (`.zshrc`, `.gitconfig`, etc.), and a dotfiles repo is a way to version control them so you can restore your entire setup on a new machine.
Athanasia Monika Mowinckel (Mon,) studied this question.
