This plugin enables folding by section headings in markdown documents.
I recommend installing
markdown-folding using [pathogen] or [Vundle]. Your
vimrc file must contain these lines at the very least:
set nocompatible if has("autocmd") filetype plugin indent on endif
markdown-folding plugin provides nothing more than a
foldexpr for markdown files. If you want syntax highlighting and other niceties, then go and get tpope's [vim-markdown] plugin.
