Developer Collaboration with Git and GitHub | #EsriDevTech2026

GitHub is a great collaboration tool and this technical session covers the basics of its version control system (git) using examples that do not require any experience writing code. Speakers also talk about how Esri uses GitHub features for managing projects and how you can get involved with Esri's open-source projects.
