This is more an instructional for me since I've had to setup a computer twice now so I'd rather not have to hunt down all these again.
Add hyperterm-cobalt2-theme to your plugins array. Kinda like this:
plugins: [ 'hyperterm-cobalt2-theme' ],
Update the font
fontFamily: '"Dank Mono", ...
git clone https://github.com/wesbos/Cobalt2-iterm.git
cp cobalt2.zsh-theme ~/.oh-my-zsh/themes/
git clone https://github.com/powerline/fonts cd fonts ./install.sh cd ..
