+# External access
+
+The only external access required by this charm is if it's configured to
+connect to an external backend, using the `backend` configuration option. As
+an example, if this is set to `http://mybackend.local:80`, then this charm
+will need to be able to access that hostname on port 80 to be able to serve
+content for it.
