+RKE2 vs. Kubespray Install
+--------------------------
+
+The AiaB installer will bring up Kubernetes on the server where it is run.  By default it
+uses `RKE2 <https://docs.rke2.io>`_ as the Kubernetes platform.  However, older versions of AiaB
+used `Kubespray <https://kubernetes.io/docs/setup/production-environment/tools/kubespray/>`_
+and that is still an option.  To switch to Kubespray as the Kubernetes platform, edit the
+Makefile and replace *rke2* with *kubespray* on this line::
+
+    K8S_INSTALL := rke2
