+Install `Proxmox Backup`_ Server Unattended
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+It is possible to install Proxmox Backup Server automatically in an unattended
+manner. This makes it possible to fully automate the setup of the Backup Server
+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. `Visit our wiki
+<https://pve.proxmox.com/wiki/Automated_Installation>`_ for more details and
+information on the unattended installation.
