Because Kubernetes is a complex beast with many moving parts, and learning about all those moving parts becomes more and more important as your usage grows.
Personally I've used Stackpoint.io to provision some small clusters but I was very excited to see this project because deploying my own cluster from scratch is next on my todo list. Kelsey Hightower's "Kubernetes the Hard Way"[1] is the canonical go-to reference here but it's also very daunting so this looks like a great middle ground.
Let's face it, even today the k8s docs can be quite sparse sometimes or gloss over the details, so knowing how all of the pieces work from the ground up can be a big help. Plus, you prevent vendor lock-in when whatever automated tool you're using doesn't solve your use-case or decides to start charging a lot of money.
