 runtime from a file. First you need to create a container image tarball. For
 example to create an image tarball for a pause container using Docker:
 ```console
-$ docker pull k8s.gcr.io/pause:3.5
-  3.5: Pulling from pause
-  019d8da33d91: Pull complete

-  Status: Downloaded newer image for k8s.gcr.io/pause:3.5

+$ docker save k8s.gcr.io/pause:3.6 -o pause.tar
 ```
 Then use `ctr` to load the container image into the container runtime:
 ```console
 # The cri plugin uses the "k8s.io" containerd namespace.
 $ sudo ctr -n=k8s.io images import pause.tar
-  Loaded image: k8s.gcr.io/pause:3.5
+  Loaded image: k8s.gcr.io/pause:3.6
 ```
 List images and inspect the pause image:
 ```console
 $ sudo crictl images
