I saw the Beehaw.org post, and noted in the first day here that a big barrier to bringing my Reddit community over is that we have a pretty extensive wiki. It seems that in general this docs.<lemmy address> does not exist, is this something mods have to turn on somewhere? Is it something admins have to turn on for the whole instance? Or is this something custom that Beehaw has done which is totally unrelated to/outside of the framework of lemmy and just happens to share an address?
As Osrs said previously, there are a ton of self-hosted wiki solutions. I’m partial to WikiJS myself.
I do understand that not everyone may want to self-host a Wiki Server though, and especially if the mods aren’t also server admins it could get difficult to have matching TLDs for the Wiki and its respective community.
Mediawiki (the engine that runs Wikipedia) is already self hostable, not sure why you’d need federation on top of that
Lemmy does not have a built-in wiki feature. docs.beehaw.org is a separate website hosted using GitHub pages, with the source available here: https://github.com/beehaw-org/beehaw-org.github.io/
