+# to communicate and can silently drop traffic. You can try to use the Letsencrypt
+# salt formula (https://github.com/saltstack-formulas/letsencrypt-formula) to try to
+# automatically obtain and install SSL certificates for your instances or set this
+# variable to "no", provide and upload your own certificates to the instances and
+# modify the 'nginx_*' salt pillars accordingly
