The Markdown syntax is designed to co-exist with HTML, so you can set up input formats with both HTML and
Markdown support. It is also meant to be as human-readable as possible when left as "source".
- Move the entire "markdown" directory into your Drupal installation's sites/all/modules folder (or your site specific directory).
- Enable the module on Administer >> Site building >> Modules
- Set up a new input format or add Markdown support to an existing format at Administer >> Site configuration >> Input formats
