What is Gollum?

Gollum is a simple, modular, and flexible wiki system built using Git as its backend. One of its most enticing features is its support for Markdown, a lightweight markup language that allows users to format text with ease. Created originally by the GitHub team, Gollum serves not just as a typical wiki but as a documentation engine that embraces the principles of version control and collaborative content creation.

History and Evolution

Gollum was born out of necessity. The rise of collaborative projects in software development highlighted the need for a way to document code and related information effectively. By leveraging Git, Gollum ensures that all changes are tracked and reversible, allowing for a dynamic and fluid workflow. Since its inception, Gollum has seen a variety of updates and improvements, refining its features and usability.

  2. Version Control: By using Git, Gollum ensures that every change made is tracked. This feature allows multiple users to collaborate on the same document simultaneously without fear of overwriting each other's work. You can view the history of changes, revert to earlier versions, or even create branches for experimental edits.

  3. Pluggable Architecture: Gollum is designed with extensibility in mind. Users can easily add new features through plugins, allowing for personalized functionality tailored to specific needs.
