Scott Chacon has been working on a side project for about eight months, resulting in the book "Pro Git," which he wrote after being approached by Apress to cover the topic of Git. Despite underestimating the workload, Chacon published the book online under a Creative Commons noncommercial 3.0 license, allowing readers to access it freely at http://progit.org. The printed version will be available soon, but the content, including markdown files and images, is accessible on GitHub, fostering community contributions such as translations into Chinese, Portuguese, and Ukrainian. He expresses appreciation for GitHub's platform, which enables collaborative improvements and translations. Chacon encourages users to purchase a copy if they frequently use the online resource, acknowledging his royalties but emphasizing the broader benefit of open licensing for the community. The Pro Git website itself is a GitHub Pages site generated with Jekyll, highlighting the integration of Git technologies in its development.
