You state " Each node has a Kubelet, which is an agent for managing the node and communicating with the Kubernetes control plane."

You then state "A Kubernetes cluster that handles production traffic should have a minimum of three nodes because if one node goes down, both an [etcd] member and a control plane instance are lost, and redundancy is compromised."

What is an etcd member? and how are there multiple instances of the control plane if there's only one control plane?

You then state "Minikube is a lightweight Kubernetes implementation that creates a VM on your local machine and deploys a simple cluster containing only one node."

The whole point of this page is to describe how Minikube is used to create a cluster only to find out that it can only create a single node 'cluster' if you can even call it that.
