 The following command starts an AIS cluster in a Docker container with a single disk (requires at least one disk) that is mounted under a temporary directory on the host:
 
 ```
-docker run -d \
-  -p 51080:51080 \
-  -v $(mktemp -d):/ais/disk0 \
-  aistorage/cluster-minimal:latest
+docker run -d -p 51080:51080 -v $(mktemp -d):/ais/disk0 aistorage/cluster-minimal:latest
 ```
 
 > Note the command exposes the host `51080` port. It is possible to reach the cluster with `http://localhost:51080` if you are on the host machine.
 
 > The above command, and all subsequent commands, assume that all volumes will be mounted in `/ais/*` directory.
 
-You can check the status of the AIS cluster on the now running Docker instance (using local host endpoint) as follows:

+In the `ais show cluster` output - a sample below - notice software versions and various other minor details. But most of all note that this is one truly minimalistic cluster: a single gateway and a single storage node:
