We also use WikiJS, it is great. The fact that all the articles are stored and checked into Git in the background is great for keeping track of who edits what, undoing accidental changes, and keeping the wiki content agnostic to the platform. That being said, there is room for improvement. Image handling is not great, and a lot of the components feel simplistic and could be fleshed out (permissions, indexing/search). Dead simple to set up though, especially with Docker-compose.
