How to setup self hosted wiki for your startup

We used Dokuwiki in a similar situation. It's been a few years since I last used it (new client uses confluence) but I remember it was super easy to connect external tools. If your script can output text, Dokuwiki can display it :)

EDIT: I decided to try dokuwiki in Podman, works nicely as long as you run:

  podman unshare chown 1000:1000 /path/to/wiki/data

Is this a good choice for a company? These sorts of "hacker" solutions inevitably fall flat because people want a bunch of bells and whistles and don't mind things like never being able to find anything (arguably the single most important feature of a wiki) or being able to integrate their documentation with other systems.
