Gollum is a wiki software using git as the back end storage mechanism, and written mostly in Ruby. It started life as the wiki system used by the GitHub web hosting system.[2][3] 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.[4] 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.[5]

Formats supported

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.[6]



Editing the pages can be done via the provided web interface, via its API or with a text editor directly in the git repository.
