+Cron setup
+----------
+To automatically check the site status and/or module updates on cron, you will
+need to install drush and configure the following tasks in the crontab:
+
+# Check ALL sites for updates, once a day starting at 0100H at night.
+0 1 * * *    /path/to/drush -r /path/to/docroot prod-monitor-updates -y --quiet
+# Fetch ALL site data every five minutes (or whatever you please obviously).
+0/5 * * * *    /path/to/drush -r /path/to/docroot  prod-monitor-fetch -y --quiet
+
+Obviously, the time and frequency of these cron jobs is at your discretion.
+Do note that, depending on the number of sites you have configured, the crons
+may be running for quite some time, especially the module update checking job!

+APC/OPcache
+-----------
 Production Check complains about APC not being installed or misconfigured. What
 is APC you wonder? Well, APC is an opcode caching mechanism that will pre-com-
 pile PHP files and keep them stored in memory. The full manual can be found
 here: http://php.net/manual/en/book.apc.php .
-For Drupal sites, it is important to tune APC in order to achieve maximum per-
-formance there. Drupal uses a massive amount of files and therefore you should
-assign a proper amount of RAM to APC. For a dedicated setup 64Mb should be
-sufficient, in shared setups, you should easily double that!

 much more.
