+## Ingress and HTTPS
+Unifi does [not support HTTP][unifi] so if you wish to use the guiService, you
+need to ensure that you use a backend transport of HTTPS.
+
+An example entry in `values.yaml` to achieve this is as follows:
+```
+ingress:
+  enabled: true
+  annotations:
+    nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
