-# Kubespray on KVM Virtual Machines hypervisor preparation
-
-A simple playbook to ensure your system has the right settings to enable Kubespray
-deployment on VMs.
-
-This playbook does not create Virtual Machines, nor does it run Kubespray itself.
-
-## User creation
-
-If you want to create a user for running Kubespray deployment, you should specify
-both `k8s_deployment_user` and `k8s_deployment_user_pkey_path`.
