Peter Kaminski says: Note, it won't feel much like a wiki if you don't use something that is link aware, like [Obsidian](https://obsidian.md) or [GitJournal](https://github.com/GitJournal). (I've used Gollum Wiki as a Massive Wiki client, and it mostly works. https://github.com/gollum/gollum )
Obsidian [Obsidian.md](https://obsidian.md) is a business built in the open by a couple of University of Waterloo grads, making use of the same back-end organization, with ambitions to go bigger. They have commercial licensing (essentially $50/person perpetual?) and ambitions. Reading their proposal page is actually almost a leaf from my **Outrage** list - Delight and Outrage - related to the frustration of programmers with note taking.
A note on Gollum is that its back-end is Ruby over Git (or on Windows, JRuby over Git).
This is one place to start: clone the Massive Wiki project, get a copy of Obsidian, open the local project as an Obsidian Vault. https://github.com/Massive-Wiki/massive-wiki/blob/main/Massive%20Wiki%20Starter%20Guidebook/2.%20Open%20a%20Massive%20Wiki%20on%20Your%20Computer.md
