What it does
Gollum is a wiki system built on Git. Its official repository describes a wiki as a repository of editable text and markup files, with optional files such as images and PDFs. Pages can be edited through a built-in web interface or a preferred editor and changes become visible after committing.
Keep wiki pages in the repository
A team can start with a Git repository for its wiki, add text or markup files as pages, and include related images or PDFs. Gollum's project describes both a built-in browser editor and the option to edit files in another tool, with version history and rollback available through Git. It also mentions diagrams and mathematical notation among the documented page content.
The Git model is valuable when contributors already understand commits and branches, but it places repository setup and maintenance on the team. Review the project's installation guide and compatibility notes before choosing a deployment. No repository was initialized and no Gollum server was run.
