GitHub is collaborating with CoderDojo to introduce coding classes for children in the United States, starting in San Francisco, with the goal of teaching kids aged 7-18 programming skills such as HTML, CSS, and JavaScript. These free sessions are conducted by professional instructors and offer a mentor for every three participants to foster a supportive environment for learning and inquiries. The inaugural session will be held at GitHub's San Francisco office, emphasizing the importance of being enthusiastic and respectful, encapsulated in the requirement to "be cool." Laptops are available for those who need them, and spaces are limited due to expected high demand.
