how_to_use.md

This .vimrc is designed to work with MacVim, but works pretty well with vanilla Vim too.

It was inspired by Janus and YADR. I decided to maintain my own .vimrc instead of using these great tools once I understood how YADR was using Vundle it to manage customizations (and saw that it wasn't that complex).

When you add a Vundle to the .vimrc, you do:

vim +BundleInstall +qall

You can debug where key mappings are coming from via:

:verbose map [keycombo]
OR
:map [keycombo]
