 Bootstrapping a cluster involves the following steps:
 
-. The bootstrap machine boots and starts hosting the remote resources required for the master machines to boot. (Requires manual intervention if you provision the infrastructure)
-. The master machines fetch the remote resources from the bootstrap machine and finish booting. (Requires manual intervention if you provision the infrastructure)
-. The master machines use the bootstrap machine to form an etcd cluster.
-. The bootstrap machine starts a temporary Kubernetes control plane using the new etcd cluster.
-. The temporary control plane schedules the production control plane to the master machines.
+. The bootstrap machine boots and starts hosting the remote resources required for the control plane machines to boot. (Requires manual intervention if you provision the infrastructure)
+. The bootstrap machine starts a single-node etcd cluster and a temporary Kubernetes control plane.
+. The control plane machines fetch the remote resources from the bootstrap machine and finish booting. (Requires manual intervention if you provision the infrastructure)
+. The temporary control plane schedules the production control plane to the production control plane machines.
+. The Cluster Version Operator (CVO) comes online and installs the etcd Operator. The etcd Operator scales up etcd on all control plane nodes.
 . The temporary control plane shuts down and passes control to the production control plane.
 . The bootstrap machine injects {product-title} components into the production control plane.
 . The installation program shuts down the bootstrap machine. (Requires manual intervention if you provision the infrastructure)
