 By default containers are run as user `root`.
 However the `podman` (uid/gid 1000) user can be used instead for which also a subuid/gid mapping is configured with the image (as described within the binary installation section below). 
 
-The storage directory within the container depends on the user's `HOME` directory:

-| User | Storage directory |
-| ---- | ----------------- |
-| `root` | `/var/lib/containers/storage` |

 Please note that, when running non-remote podman within a docker container, the docker container needs to be `--privileged`.
 
 ### Container usage example
 
 Run podman in docker:
 ```sh
-docker run --privileged mgoltzsche/podman:rootless docker run alpine:latest echo hello from nested container
+docker run --privileged -u podman:podman mgoltzsche/podman:minimal docker run alpine:latest echo hello from nested container
 ```
