+# NAME
+podman-play-kube - Create pods and containers based on Kubernetes YAML
+
+# SYNOPSIS
+**podman play kube **
+[**-h**|**--help**]
+[**--authfile**]
+[**--cert-dir**]
+[**--creds**]
+[***-q** | **--quiet**]
+[**--signature-policy**]
+[**--tls-verify**]
+kubernetes_input.yml
+
+# DESCRIPTION
+**podman play kube** will read in a structured file of Kubernetes YAML.  It will then recreate
+the pod and containers described in the YAML.  The containers within the pod are then started and
+the ID of the new Pod is output.
+
+Ideally the input file would be one created by Podman.  This would guarantee a smooth import and expected results.
+
+# OPTIONS:
+
+**--authfile**
+
+Path of the authentication file. Default is ${XDG_RUNTIME\_DIR}/containers/auth.json, which is set using `podman login`.
+If the authorization state is not found there, $HOME/.docker/config.json is checked, which is set using `docker login`.
+
+Note: You can also override the default path of the authentication file by setting the REGISTRY\_AUTH\_FILE
+environment variable. `export REGISTRY_AUTH_FILE=path`
+
+**--cert-dir** *path*
+
+Use certificates at *path* (\*.crt, \*.cert, \*.key) to connect to the registry.
+Default certificates directory is _/etc/containers/certs.d_.
+
+**--creds**
+
+The [username[:password]] to use to authenticate with the registry if required.
+If one or both values are not supplied, a command line prompt will appear and the
+value can be entered.  The password is entered without echo.
+
+**--quiet, -q**
+
+Suppress output information when pulling images
+
+**--signature-policy="PATHNAME"**
+
+Pathname of a signature policy file to use.  It is not recommended that this
+option be used, as the default behavior of using the system-wide default policy
+(frequently */etc/containers/policy.json*) is most often preferred.
+
+**--tls-verify**
+
+Require HTTPS and verify certificates when contacting registries (default: true). If explicitly set to true,
+then TLS verification will be used. If set to false, then TLS verification will not be used. If not specified,
+TLS verification will be used unless the target registry is listed as an insecure registry in registries.conf.
+
+**--help**, **-h**
+
+Print usage statement
+
+## Examples ##
+
+Recreate the pod and containers as described in a file called `demo.yml`
+```
+$ podman play kube demo.yml
