1. clone into ~/.dotfiles
2. ./setup.sh

note this uses a detached working directory. The setup script aliases dgit to git --git-dir ~/.dotfiles/.git --work-tree=$HOME before running dgit reset --hard from the home directory. This means the repo is stored in .dotfiles, but after the reset, git moves its files to the root of the home directory.

Add new files to ~/.dotfiles and use dgit for any git commands.
