“Version control is a critical tool in the developer’s tool chain. So it’s disappointing to consider just how few developers actually understand their version control system beyond the minimal incantations required merely to survive a day of coding at the office. Thanks to Eric Sink’s new book on the topic, this need be the case no longer. Version Control by Example is organized well, light in tone, yet saturated with practical illustrations of not only how to choose among and use today’s most popular free version control tools, but how to do so with efficiency, understanding, and purpose.”
