Git & GitHub 101: A Beginner's Guide to Version Control

Short summary

Git is a distributed version control system that saves code snapshots; GitHub is the cloud platform for hosting and collaborating on repositories. The five essential commands—add, commit, push, pull, and branch—let you track changes, revert mistakes, and work safely with teams. Branches create isolated experimental versions that don't affect stable main code until you merge them back.
