cronjobs with wget

Hello..i am running nginx on Centos 7 with wget instead of get and am not sure how to alter the provided crontab info at http://learn.elgg.org/en/stable/admin/cron.html. Location of  LWPR='/usr/bin/lwp-request' is correct but not sure about the changes to GET for wget. I am presuming the info once correct goes into the root crontab file. My Vestacp crontab is called admin and it handles all the crons from vesta so not sure which to use.
