-This plugin implements the [[ikiwiki/directive/calendar]] [[ikiwiki/directive]].
+This plugin provides a [[ikiwiki/directive/calendar]] [[ikiwiki/directive]].
The directive displays a calendar, similar to the typical calendars shown on
some blogs.
+
+Since ikiwiki is a wiki compiler, to keep the calendar up-to-date,
+wikis that include it need to be periodically refreshes, typically by cron
+at midnight. Example crontab:
+
+ 0 0 * * * ikiwiki -setup ~/ikiwiki.setup -refresh
+
+## CSS
