Ask HN: Markdown-capable wiki software?

Gollum

It's the wiki that powers Github, so you use it with Git and it's markdown enabled. I thought it was a pretty great tool

http://www.WikiMatrix.org compares wiki software. http://goo.gl/saome shows the "Top 25 Wikis" Markdown support.

I think Ikiwiki will do Markdown. Have not used Ikiwiki myself, but was quite impressed with their page on security, which is a good sign of overall competence.

I use ikiwiki extensively and it's exactly what you want, and incredibly awesome and fully featured.
