ALT A row of 6 cute smiling monsters celebrating using GitHub. The first, wearing a climbing harness labeled “Me” is high-fiving another whose harness says “Future Me”. Others hold a box of snacks that are tacos, a map, and a rope. Text above the monsters quotes Jenny Bryan: “Collaboration is the most compelling reason to manage a project with Git and GitHub. My definition of collaboration includes hands-on participation by multiple people, including your past and future self, as well as an asymmetric model, in which some people are active makers and others only read or review.”
