+[Subversion](http://subversion.tigris.org/) is a revision control system. While ikiwiki is relatively
+independent of the underlying revision control system, and can easily be
+used without one, using it with Subversion is recommended since it's how
+the author uses it. ([[Git]] is another option.)
+
+Ikiwiki can run as a [[post-commit]] hook to update a wiki whenever commits
+come in. When running as a [[cgi]] with Subversion, ikiwiki automatically
+commits edited pages to the subversion repostory, and uses the Subversion
+log to generate the [[RecentChanges]] page.
