I went ahead and bought the book from interest in helm (quite the beginner in k8 and all). Unfortunately it's not very far from an AI generated text about helm. It's 28 pages of text (not far from a long blog post), it does not have any illustration. The author does not seem to have given any thought on how to explain the topic. A discussion with claude about the topic is of higher value.

Would not recommend.

For the record this is about "Kubernetes Helm," not "Emacs Helm," sadly. :)
