This set up creates a bare repository in your home directory to track dot files.

• https://www.atlassian.com/git/tutorials/dotfiles

alias config='/usr/bin/git --git-dir=$HOME/.files/ --work-tree=$HOME'
echo ".files" >> .gitignore # to avoid weird recursion
git clone --bare <git-repo-url> $HOME/.files
config checkout
config config --local status.showUntrackedFiles no

Lastly set up global git identity: https://git-scm.com/book/en/v2/Getting-Started-First-Time-Git-Setup
