Build me a simple Kubernetes cluster setup guide for kubeadm.

I want this repo to help someone set up a working cluster from scratch on a few Linux machines, with clear steps for the control plane and worker nodes, plus any basic prep like container runtime, networking, and join commands. Keep it easy to follow, like something a person could use while setting up a real cluster by hand.

Please make the instructions practical and copy paste friendly, and organize them so the flow is obvious from start to finish. Include any checks to confirm the cluster is healthy after setup, and add notes for the common things that usually go wrong during a first install.

If there are current best practice details that matter, look up the latest docs online and use those.
