I'm looking for something a bit more powerful than the Wiki bundled with GitLab (which uses Gollum). I started with MkDocs but moved it over to GitLab Wiki because I thought the instant feedback. I now have mixed feelings.

I've used Hugo in the past for a few sites, but the amount of boilerplate required, even though minimal, is a bit of a hurdle for an internal wiki.

Has anyone been here? Suggestions?

It's great, the directory structure is straightforward and even supports search (through lunr.js) out of the box.
