Software recommendations please. I want to throw up a wiki or etherpad style thing on my server. Must be FOSS. Doesn't need to be complex. Preferably installable via apt on a Debian Stable server. I know HZ has a wiki and I can probably do this via a Nextcloud app, but I want it to be separate from both these (the documents will be edited by a large group and I don't want to run that many HZ/NC accounts).
