+# this is an example nginx config for zammad with free letsencrypt.org ssl certificates
+# replace all occurrences of example.com with your domain
+# when creating letsencrypt certificates the first time comment out the https parts in the config or nginx will not start
+# create letsencrypt certificate by: /usr/bin/letsencrypt certonly --rsa-key-size 4096 --duplicate --text --webroot-path /var/www/html/ --webroot -d example.com -d www.example.com
+# create dhparam.pem by: openssl dhparam -out /etc/nginx/ssl/dhparam.pem 4096
+# download x3 certificate by: wget -q https://letsencrypt.org/certs/lets-encrypt-x3-cross-signed.pem -P /etc/nginx/ssl
+# you can test your ssl configuration @ https://www.ssllabs.com/ssltest/analyze.html
