+
+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
