I’m looking for a wiki solution (either remotely hosted or self-hosted is fine) that takes Markdown input.
Thanks.
Dokuwiki has a plugin that lets you use markdown instead of their proprietary markup.
+1 Dokuwiki. It is a little complicated than most to configure the first time, but once you have everything running, it will work without complaints. Also, the whole wiki is stored as plain text files, which is awesome for backups.
