The Kubernetes the Hard Way tutorial is well documented and useful, but it assumes readers already understand Kubernetes and how its major components fit together. Would it be worth adding more explanation near the beginning about the overall architecture, the role of components such as the control plane, etcd, and kubelets, and the design decisions behind each step? The tutorial also appears to choose or default many plugin and configuration options without discussing the alternatives. More context could help readers understand what they are building instead of simply following the commands, while still preserving the hands-on nature of the guide.

Trying to combine a complete conceptual introduction with a detailed implementation guide could make both parts harder to follow. A short architecture overview or a separate beginner resource paired with the tutorial may be a better approach than expanding every step in the guide.
The tutorial is intentionally focused on building and administering a cluster, not introducing Kubernetes from scratch. It works best if you first learn the basic roles of the control plane, etcd, kubelet, and networking components, then use the tutorial to see how those pieces are assembled manually.
That makes sense. My concern is less about making the steps easier and more about understanding why particular architectural and plugin choices were made.
The tutorial necessarily presents one working reference configuration. Real Kubernetes deployments involve choices about networking, container runtimes, storage, certificates, and other plugins, but explaining every alternative would make the walkthrough much longer and less repeatable. Treat the commands as an example implementation, then study the available options separately before designing a production cluster.
A brief prerequisites section covering the major components and decisions would probably provide enough context without turning the guide into a different kind of course.
