Message from acme.sh-3.0.9:

This script will create the following directories if they do not exist:

~acme/.acme.sh
~acme/certs

The script will also install ~acme/.acme.sh/account.conf.sample which has
sane defaults. Copy this to ~acme/.acme.sh/account.conf and edit contents
to suit.

If you have EXAMPLES on:

• In the /usr/local/share/examples/acme.sh directory, you can find the dnsapi scripts which will be useful if you decide to use dns-01 challenges. Also included are the deploy scripts.

• A newsyslog.conf sample file is installed at /usr/local/etc/newsyslog.conf.d/acme.sh.conf - you must modify it by at least uncommenting the line.

• If you run newsyslog -NC it will create the required logfiles.

• Please review /usr/local/share/examples/acme.sh/acme.sh-cron.d - instructions are contained in that file.
