 ### Using it from CRON
 
-If you want to use plexupdate as either a cron job or as a [systemd job](https://github.com/mrworf/plexupdate/wiki/Running-plexupdate-daily-as-a-systemd-timer), the -c option should do what you want. All non-error exit codes will be set to 0 and no output will be printed to stdout unless something has actually been done. (a new version was downloaded, installed, etc)
+Generally, you copy the cronwrapper from the extras folder into the ```/etc/cron.weekly``` and edit the script to suite your needs. It  will require you to create a configuration file (or at least, it's highly recommended). It also provides logging via syslog if needed. Should the script fail, it will print why and in most cases, this will result in an email to you.
 
-If you don't even want to know when something has been done, you can combine this with the -q option and you will only receive output in the event of an error. Everything else will just silently finish without producing any output.
