+# WARNING: This service does not use the --resume flag, so if you
+# use the API to make changes, they will be overwritten by the
+# Caddyfile next time the service is restarted. If you intend to
+# use Caddy's API to configure it, add the --resume flag to the
+# `caddy run` command or use the caddy-api.service file instead.
