Firstly, thank you so much for writing this awesome guide which helped me understand much of the current state of web push notification.

Type of Issue

Suggestion about the book site layout

Details....

I see that the content of this book is similarly available at Google Developer's site: https://developers.google.com/web/fundamentals/push-notifications/how-push-works There, at each chapter, there are clear list of chapter navigation at the left side of the page and list of contents available at the right side of the page which makes navigation easier (albeit a bit cluttered).

Meanwhile, at this book website, the possible navigation at each page is just backward and forward (indicated by the arrows), and here reader does not know what page is expected by going back or going forward. One use case is that sometimes, when reading the book site, I'd like to skip some pages or go to a specific page for reference, but just couldn't easily find it due to the current navigation constraint. Hence, my suggestion is to include a list of chapters at each pages to make navigation to other chapter easier. Thank you 😁

Totally agree, I've had this on my to-do list for some time and I'm hoping to get some time this weekend to work on new content + this issue :)
