+
+## NAME
+podman\-pod\-create - Create a new pod
+
+## SYNOPSIS
+**podman pod create** [*options*]
+
+## DESCRIPTION
+
+Creates an empty pod, or unit of multiple containers, and prepares it to have
+containers added to it. The pod id is printed to STDOUT. You can then use
+**podman create --pod <pod_id|pod_name> ...** to add containers to the pod, and
+**podman pod start <pod_id|pod_name>** to start the pod.
+
+## OPTIONS
+
+**-a**, **--attach**=[]
+
+Not yet implemented.
+
+**--cgroup-to-ctr**=""
+Tells containers in this pod to use the cgroup created for the pod
+
+**--cgroup-parent**=*true*|*false*
+
+Path to cgroups under which the cgroup for the pod will be created. If the path is not absolute, the path is considered to be relative to the cgroups path of the init process. Cgroups will be created if they do not already exist.
+
+**--podidfile**=""
+
+Write the pod ID to the file
+
+**--help**
+
+Print usage statement
+
+**-l**, **--label**=[]
+
+Add metadata to a pod (e.g., --label com.example.key=value)
+
+**--label-file**=[]
+
+Read in a line delimited file of labels
+
+**-n**, **--name**=""
+
+Assign a name to the pod
+
+The operator can identify a pod in three ways:
+UUID long identifier (“f78375b1c487e03c9438c729345e54db9d20cfa2ac1fc3494b6eb60872e74778”)
+UUID short identifier (“f78375b1c487”)
+Name (“jonah”)
+
+podman generates a UUID for each pod, and if a name is not assigned
+to the container with **--name** then the daemon will also generate a random
+string name. The name is useful any place you need to identify a pod.

+## NAME
+podman\-pod\-rm - Remove one or more pods
+
+## SYNOPSIS
+**podman rm** [*options*] *container*
+
+## DESCRIPTION
+**podman pod rm** will remove one or more pods from the host.  The pod name or ID can be used. The -f option stops all containers then removes them before removing the pod. Without the -f option, a pod cannot be removed if it has attached containers.
+
+## OPTIONS
+
+**--force, f**
+
+Stop running containers and delete all stopped containers before removal of pod.
+
+**--all, a**
+
+Remove all pods.  Can be used in conjunction with -f and -r as well.
+
+## EXAMPLE
