I don't understand when I have to run this command. Just to make sure first I have to install acme.sh and then issue a cert following acme.sh instructions? So when should I run ./acmetool.sh acmeinstall command? I also don't have any file on /etc/centminmod/custom_config.inc, should I create it? Once I add that line, debug mode will be enabled, but I already have option 22 in centmin menu...so which will be the difference?
