This uses yadm, which is basically a lightweight wrapper around git to store your config files in a repo. There are other ways of managing your dotfiles with more generic tools, but yadm is lightweight enough and offers enough "just works" that its worth it.
This is standard yadm stuff copied here for convenience.
# Install yadm on your system
brew install yadm
# Clone py repo
# or yadm clone git@github.com:BrianPugh/dotfiles.git if you're me.
yadm clone https://github.com/BrianPugh/dotfiles.git
# runs my installation script located at ~/.config/yadm/bootstrap
yadm bootstrap
# Install yadm on your system
sudo apt install yadm
# Clone py repo
# or yadm clone git@github.com:BrianPugh/dotfiles.git if you're me.
yadm clone https://github.com/BrianPugh/dotfiles.git
# runs my installation script located at ~/.config/yadm/bootstrap
yadm bootstrap
