I do not yet have enough experience with the one time setup scripts under setup/.
You should therefore cherry pick the things that you actually require.
The actual bash configuration can be linked in the following way:
git clone git@github.com:bripkens/dotfiles.git ~/.dotfiles
bash "~/.dotfiles/link"
My dotfiles are heavily inspired by Mathias Bynens' and Ben Alman's dotfiles and many other great blog posts on the web. Thanks guys!
