Ikiwiki can run as a git `post-update` hook to update a wiki
whenever commits come in. When running as a [[cgi]],
ikiwiki automatically commits edited pages, and uses the
-git history to generate the [[Json.tl.ph]] page.
+git history to generate the [[RecentChanges]] page.
Normally you can just follow the instructions in [[setup]] to create
the git repositories and get started. To understand the details, read on.
