Are you new to Git and GitHub? Would you like to learn the basics but haven't taken the time to read the GitHub Help pages yet? Sit back and watch this 50 minute course entitled "The Basics of Git & GitHub," recorded from a live webinar with Matthew McCullough of GitHub:Training and with chat commentary from Brent Beer. This class assists students in using Git from the command line and offers a quick glimpse of the GitHub for Windows and GitHub for Mac GUIs. It offers GitHub newcomers a tour of what this feature-loaded version control tool and an equally powerful web application can do for developers, designers, and managers in both the open source and commercial software worlds.
