While the examples in this book use HTML5, Node.js, and CouchDB, this book should not be used as a source for learning these technologies. Astute readers may find the author’s use of these tools—HTML5, Node.js, CouchDB—somewhat stilted and possibly, to some, blasphemous. The author makes no claims at expertise in these technologies. Instead, in the context of this book, they are used as tools for illustrating points about hypermedia design and implementation. The appendices list several good books on the technologies used in the writing of this text that the reader is encouraged to refer to for a more authoritative voice on these matters.

This book does not cover the details of the HTTP protocol and associated web standards. There is a wealth of writing available and the appendices reference important RFCs and other standards documents used while preparing this text. The reader will also find several book recommendations in the appendices well worth the time to read and become acquainted.
