Ever struggled with tracking changes in your code or collaborating without overwriting someone else's work? Git is the industry-standard tool for version control, but its cryptic commands can feel overwhelming at first. In this 15-minute session, you'll discover what Git actually is, why researchers and developers rely on it, and how platforms like GitHub and GitLab make collaboration possible. Through hands-on examples, we'll demonstrate some essential skills whether you're coding solo or working in a team. After this introduction material to get you started with Git will be provided. My name is Christian Toderascu, working as a PhD in computational mechanics at BATir, and I'm going to show you how I use Git.
