A new interactive course has been launched on Code School, allowing beginners to try Git and GitHub without any software installation. The course, available at try.github.com, is designed for developers, designers, and other knowledge workers who are new to these tools, and it only takes about 15 minutes to complete. It integrates with GitHub through OAuth and creates a tutorial repository named "try_git" in the user's GitHub account. Additionally, it pairs well with introductory Git videos available on the Git SCM site, providing a comprehensive learning experience for newcomers. The initiative is authored by Matthew J. McCullough.
