$ vim ~/.vimrc
set nocompatible " be iMproved, required
filetype off " required
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'
call vundle#end() " required

" To ignore plugin indent changes, instead use:
"filetype plugin on
" Put your non-Plugin stuff after this line
