Note that this module depends on the [Parsedown](http://parsedown.org/) Parser and the [HTMLPurifier](http://htmlpurifier.org/) filter. These libraries should be downloaded from their sites and installed in the swarm/library/ folder. Parsedown.php must be placed in the swarm/library/Parsedown/ path. The HTMLPurifier [standalone](http://htmlpurifier.org/download#Standalone) distribution should be placed in the /swarm/library/HTMLPurifier/ path, with HTMLPurifier.standalone.php accessible in that path. As usual, the contents of the module folder should be in swarm/module/Markdown/ and the contents of the public folder should be placed in swarm/public/custom/Markdown/
