	Use:   "zones",

serves it.

This is also the quickest way to check that credentials, context and network
path are all working: it is read-only and touches nothing.

The name server shown is the value the gateway requires when changing
records, so this is what the write commands rely on.`,
	Example: `  # every zone
  schlundtech-dns zones

  # one zone per line, for scripting
  schlundtech-dns zones --output json`,
