# How to use "acme.sh" to set up Lets Encrypt without root permissions
# See https://github.com/Neilpang/acme.sh for more

# This assumes that your website has a webroot at "/var/www/<domain>"
# I'll use the domain "EXAMPLE.com" as an example

# When this is done, there will be an "acme" user that handles issuing,
# updating, and installing certificates. This account will have the following
# (fairly minimal) permissions:
#   - Host files at http://EXAMPLE.com/.well-known/acme-challenge
