Making my terminal look exactly the way I want because I'm picky and can never actually remember how I set it up in the first place:
Run install.sh, first off. This will create the symlinks, download vim-plug and install plugins, and for local development, install fonts and iTerm colorscheme.
Since you're trying to replicate my dev setup, you're going to want to install tmux.
I use iTerm2, with the color scheme Monokai Soda and 13pt Inconsolata font. You may need to play with the character spacing a little to get the Powerline glyphs to look good.
One million years ago, when I was a new vim user, DeMarko bequeathed unto me his vimrc. A lot of the clever stuff in here is from his verison, and I am also grateful for his help while I was cleaning it up to remove things I don't actually use!
