-The `calendar_autocreate` [[setup option|plugins/calendar]] can be used to
-automatically generate the archive pages.
+## Generating archive pages
+
+If [[!iki plugins/calendar desc=option]] `calendar_autocreate` is not set, the
+[[!iki ikiwiki-calendar]] command can be used to automatically generate the archive
+pages. It also refreshes the wiki, updating the calendars to highlight the
+current day. This command is typically run at midnight from cron.
+
+An example crontab:
+
+ 0 0 * * * ikiwiki-calendar ~/ikiwiki.setup "posts/* and !*/Discussion"
+
+
+With [[!iki plugins/calendar desc="setup option"]] `calendar_autocreate`,
+all this work is done by `ikiwiki` itself. Thus, the crontab command can be
+replaced by:
+
+ 0 0 * * * ikiwiki --setup ~/ikiwiki.setup --refresh
