 ## DESCRIPTION
-The attach command allows you to attach to a running container using the container's ID
-or name, either to view its ongoing output or to control it interactively.
-
-You can detach from the container (and leave it running) using a configurable key sequence. The default
-sequence is `ctrl-p,ctrl-q`.
-Configure the keys sequence using the **--detach-keys** option, or specifying
-it in the **containers.conf** file: see **containers.conf(5)** for more information.

 ### 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`.
