+Combination of Plugins
+^^^^^^^^^^^^^^^^^^^^^^
+
+Combining `http-01` and `dns-01` validation is possible in case your node is
+reachable via multiple domains with different requirements / DNS provisioning
+capabilities. Mixing DNS APIs from multiple providers or instances is also
+possible by specifying different plugin instances per domain.
+
+TIP: Accessing the same service over multiple domains increases complexity and
+should be avoided if possible.

+Automatic renewal of ACME certificates
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If a node has been successfully configured with an ACME-provided certificate
+(either via pvenode or via the GUI), the certificate will be automatically
+renewed by the `pve-daily-update.service`. Currently, renewal will be attempted
+if the certificate has expired already, or will expire in the next 30 days.
