Lesson 1 / 20
What is GitHub?
Learn how GitHub builds on Git as a hosting and collaboration platform with pull requests, issues and Actions.
Git vs GitHub
Git is the version-control tool that runs on your machine. GitHub is a cloud service that hosts Git repositories and adds collaboration features on top — pull requests, issues, code review.
A shared home for your repo
Git is like a personal diary you keep on your laptop. GitHub is like publishing that diary online so teammates can read it, comment, and add their own pages.
What GitHub adds
Beyond hosting: pull requests, issue tracking, code review, CI/CD via Actions, project boards, and a social layer — stars, followers, profiles.
