This book effort was started in March 2018. The plan is to document HTTP/3 and its underlying protocol: QUIC. Why, how they work, protocol details, the implementations and more.
The book is entirely free and is meant to be a collaborative effort involving anyone and everyone who wants to help out.
A reader of this book is presumed to have a basic understanding of TCP/IP networking, the fundamentals of HTTP and the web. For further insights and specifics about HTTP/2 we recommend first reading up the details in http2 explained.
