def self.register(cli)
  cli.desc "Edit a resource configuration"
  cli.long_desc <<~HELP
    Open a VM, container, node, or volume configuration in your text
    editor. The configuration is presented as YAML for easy editing.
    Changes are applied via the Proxmox API when you save and close
    the editor.

    EXAMPLES
      Edit a VM configuration:
        $ pvectl edit vm 100

      Edit a container with a specific editor:
        $ pvectl edit container 200 --editor nano

      Edit a node configuration:
        $ pvectl edit node pve1

      Edit node DNS resolver settings:
        $ pvectl edit dns pve1

      Edit volume properties:
        $ pvectl edit volume vm 100 scsi0

      Edit /etc/hosts on a node:
        $ pvectl edit hosts pve1

      Preview changes without applying:
        $ pvectl edit vm 100 --dry-run

    NOTES
      Uses $EDITOR environment variable by default, falling back to vi.
      Override with --editor flag.

      In --dry-run mode, shows the diff between current and edited
      configuration without applying changes to Proxmox.

      Supported resource types: vm, container (ct), node, volume, dns, hosts.

      For DNS, the node identifier is given as a positional argument
      (pvectl edit dns NODE). DNS settings include search domain and
      up to three nameservers (dns1, dns2, dns3).

      For volumes, syntax is: pvectl edit volume <vm|container> <id> <disk>

      For hosts, the node identifier is given as a positional argument
      (pvectl edit hosts NODE). The /etc/hosts file is edited as raw
      text — Proxmox requires the pvelocalhost entry to remain present
      and will reject updates removing it.

      Not all configuration keys can be changed while a VM is running.
      Proxmox will reject invalid changes with an error message.
