Clone the repo with
git clone http://github.com/dodgejcr/dotfiles.git
Now move all the files where you need them. If is marked with a '.' then the file belongs in your ~/ directory
If not, it belongs in ~/.config
I have included the powerline font that you need to move to /usr/share/fonts/TTF/ If you choose not to use the font, change the font line in .Xresources
