Rick Umali's "Learn Git in a Month of Lunches" (Manning Publications Co.)

Make the hour spent stuffing your face with food productive time with Rick Umali's new book Learn Git in a Month of Lunches. In this novel "study while dining" format, Umali helps those hungry for knowledge of the diverse and sprawling beast that is Git, the source code control system preferred by distributed development teams. Each easy-to-follow lesson on the discipline of source code control using Git is designed to take an hour or less. The author's goal is to distill Git down to the essential concepts and techniques that users need to get the most out of it with a focus on stuff they'll likely use every day. Rather than cover a shallow introduction to Git's massive surface area, readers will find a road map to the commands and processes that they need to be instantly productive.
