 Beautify Markdown, fixing formatting mistakes and converting basic HTML & Unicode into their Markdown equilivants. Based on the conventions in [Carrot Creative's Markdown Styleguide](https://github.com/carrot/markdown-styleguide) and built on [Marked](https://github.com/chjj/marked).
 
 ## Features
 - standardize syntatical elements to use a single way of being written (for example, all unordered lists are formatted to start with hyphens, rather than allowing asterisks and/or addition signs to be mixed in).
 - fix numbering - making ordered lists count naturally from 1 to _n_ and reference links do the same (based on first occurance).
 - make headers move from h1 to smaller without gaps (like an `h1` followed by an `h4` would be corrected to an `h1` followed by an `h2`).
 - decode Unicode characters that have markdown equilivants (like "…" becomes "..." and "—" becomes "--").
-- move long or repeated links into the reference links section.
