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?
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/
