GitHub Wiki 'Completely Rewritten'
GitHub Announce Git-Backed Wiki System
GitHub have announced a “completely rewritten” Git-backed wiki system, where each page is a file in a directory and each change is a commit.
This new GitHub Wikis will leverage the GitHub markup library, and provide context sensitive help and a toolbar. Users will also be able to display images hosted inside the Git repository. The tools for showing the history and making comparisons remains unchanged.
GitHub are also releasing Gollum, the Ruby library that powers GitHub Wikis.
