cat <<'NOTE'

Notes:
- Operator tools are needed on your local machine to drive Railiance.
- Provisioning:
  • ansible — required to bootstrap hosts
  • kubectl/helm/kustomize — needed once Kubernetes is up
  • sops/age — for managing encrypted secrets (recommended)
  • docker or podman — only if building images locally
  • yq — handy for YAML manipulation in scripts
  • rsync/scp/tar — file transfer & packaging utilities

TIP: On Debian/Ubuntu install basics with:
  sudo apt-get update && sudo apt-get install -y \
    curl git jq python3 openssh-client ansible rsync tar
