Pubserver can be used to both host and render markdown files. Complete with templates for all markdown features, it is great for generating and/or hosting documentations and other quick publications.
Install as global package, then use the pubserver executable.
To host as an http server:
pubserver --host 127.0.0.1 -p 8008 -s /usr/share/program/docs
To prerender for static hosting(such as GitHub pages):
pubserver -r /usr/share/program/docs
