+#### Notes for SSL
+If you enable the use of existing Let's Encrypt certificates you need to open ports in your firewall to use them.
+
+If SSL is used the panel_iframe has to use the same domain name as the one issued with your certificate.
+```yaml
+panel_iframe:
+  web_terminal:
+    title: 'Web terminal'
+    icon: mdi:console
+    url: 'https://yourdomain.duckdns.org:4200'
