Patchwork is an upcoming workshop hosted at GitHub's San Francisco headquarters, designed to teach participants about Git and GitHub in a collaborative environment. Scheduled for January 29th from 6:30 to 9:00 PM, the event aims to foster learning and community building among attendees, with guidance from GitHub employees and other open source contributors serving as mentors. Participants will have the opportunity to work hands-on with Git concepts, such as creating forks and branches, and will leave with a pull request merged, equipping them to further engage with open source projects. The event promises a supportive atmosphere with snacks and networking opportunities, and those interested can sign up either as attendees or mentors.
