Redakční systém pomoc

Na internete som našiel redakční systém a knemu instalaciu.Popis inštalacie je anglicky a nije mi jasne čo treba stímto robiť?

6) Now you need to create the following Cron Jobs. We use CURL to access the URLs, but contact me if you server doesn't have CURL installed.
These cron jobs should be set to run every minute, of every hour, or every day. Make sure the cronTime in the config is set to 1 also.
The 4 commands you need to set up are:
curl -s -o /dev/null
curl -s -o /dev/null
curl -s -o /dev/null
curl -s -o /dev/null

If you are running the site on your local host, you can test these things by simply running the daemons directly on another browser
and set the cronTime to say 10 to keep it running.

Poprosil bi som návod čo to je Cron Jobs čo treba stím vlastne robiť.
Za odpoveď vopred ďakujem.
Než vysvětlovat, tak raději odpovím, že Vámi uvedený redakční systém zde nebude fungovat.
