cat <<'NEXT'

Next:
  runpool register <pool> --repo OWNER/REPO   # or --org ORG
  runpool schedule install                    # background autoscale and clean
  runpool status

Or describe every pool in ~/.config/runpool/pools and reconcile to it:
  runpool apply --dry-run                     # what would change
  runpool apply

Pools come up on their own when a job queues. Nothing starts at login.
