> How GitHub relates to Git — a hosting and collaboration layer on top of your local repository.

## 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.
