live in the Wiki for now as it applies to not just Proxmox Mail Gateway.

+Unattended Installation
+-----------------------
+
+It is possible to install {pmg} automatically in an unattended manner. This
+makes it possible to fully automate the setup of {pmg} on bare-metal. Once the
+installation is done and the host has booted up, automation tools like Ansible
+can be used to further configure the installation.
+
+The options for the installer have to be provided in an answer file. This
+answer file allows using filter rules to decide which disks and network card
+should be used. It is also possible to run custom commands in the installation
+environment prior and after the installation.
+
+It is necessary to prepare the installation ISO to be usable for the automated
+installation. https://pve.proxmox.com/wiki/Automated_Installation[Visit our wiki]
+for more details and information on the unattended installation.
