Gollum is wiki software that uses Git as the backend storage mechanism, and written mostly in Ruby. It started life as the wiki system used by the GitHub web hosting system.[1] [2] Although the open source Gollum project and the software currently used to run GitHub wikis have diverged from one another, Gollum strives to maintain compatibility with the latter.[3] Currently it is used by GitLab server to store and interconnect wiki-pages with wiki-links, but the plan is to move complete away from Gollum in the future.[4]
Gollum wikis are simply Git repositories that adhere to a specific format. Gollum pages may be written in a variety of formats including Markdown, AsciiDoc, ReStructuredText, Creole and MediaWiki markup.[5]
Editing the pages can be done via the provided web interface, via its API or with a text editor directly in the Git repository.
