+### Systemd Unit and Timer
+
+Podman ships with a `podman-auto-update.service` systemd unit. This unit is triggered daily at midnight by the `podman-auto-update.timer` systemd timer. The timer can be altered for custom time-based updates if desired. The unit can further be invoked by other systemd units (e.g., via the dependency tree) or manually via `systemctl start podman-auto-update.service`.
