~$ man github
What is GitHub (and how is it different from Git)?
definition
Git is a version control system that runs on your own machine and records every edit to your code files so you can go back to earlier versions.
GitHub is a cloud service that stores copies of those Git repositories online, making it simple to share projects and work with other people.
The main difference is location and access: Git handles local tracking while GitHub adds remote hosting, collaboration tools, and visibility.
Git is like keeping a detailed diary of every change you make to a school project on your desk. GitHub is the shared classroom folder where you upload that diary so classmates can read it, add notes, and keep their own copies in sync.
key takeaways
- Git records code changes only on your local computer.
- GitHub stores those changes in the cloud for backup and sharing.
- Pull requests on GitHub let teammates review code before it is added.
- GitHub includes issue tracking and automation features called Actions.
- Public GitHub profiles serve as visible proof of coding work for employers.

frequently asked questions
How do I upload my first project to GitHub?
Install Git locally, create a repository on the GitHub site, then run the three commands GitHub shows to connect and push your files.

What is a pull request on GitHub?
A pull request is a request to merge code changes from one branch into another. It lets teammates comment on the changes before they become part of the main project.
Do companies check GitHub profiles during hiring?
Many recruiters and hiring managers review public GitHub activity to see recent projects and contribution style. Clean commit history and clear README files help candidates stand out.
