What is the best tool for self hosted or paid WIKI / Knowledge base / FAQ?

Question

I would like to create a huge knowledge base on our site and currently, I am looking for the best solutions. We just want to have a separated WIKI / Knowledge base / FAQ from the main Blog posts without any ticketing system. Our site runs on WordPress but I also don't want to install another Theme for this. So I am looking for plugins, third party services or a SaaS like HelpDocs.

Accepted Answer

Gollum (used by the folks at GitHub) is a simple wiki system with an awesome API and local frontend that's built on top of Git.
