Ask HN: Requesting feedback for debugging CI/CD for beginners book outline

Hi. I am writing a book about debugging, speeding up, and profiling CI/CD for beginners. I would like your feedback on my outline regarding if you think this book would be useful for a beginner, and if the treatment of the topics is adequate.

I have a very messy outline here: https://docs.google.com/document/d/14iEQUTDqB-QdqEzvkvvN1qoCT0JfiNZKodfcMKaYI4w/edit

Looking forward to hearing your thoughts.
