+Switching from the `staging` to the regular ACME directory
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Changing the ACME directory for an account is unsupported. If you want to switch
+an account from the `staging` ACME directory to the regular, trusted, one you
+need to deactivate it and recreate it.
+
+This procedure is also needed to change the default ACME account used in the GUI.
+
+.Example: Changing the `default` ACME account from the `staging` to the regular directory

+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 or will expire in the next 30 days.
