-#   PRODUCTION: ./acme-cpanel-webroot.sh --force -e me@gmail.com multisites/flatwhitedesign.pw multisites/greengingermultisite.website

-# FILES is a list of files containing first-level DOMAIN names (see domains.txt) on newlines
-# Certificates will automatically be issued and deployed for DOMAIN and www.DOMAIN using the webroot method
-#
-# NOTE: The webroot method does NOT support wildcard domains, Let's Encrypt requires wildcard domains to
-# use DNS challenges, which the CPANEL uapi does not support (use dns_cpaneldns plugin instead)
