Git and GitHub for beginners: why every developer needs them

Git and GitHub are two of the first professional tools a developer learns. They are how you save the history of your code, undo mistakes, and work together with other people without overwriting each other. Almost every job posting for a developer expects you to know them.

What is Git

Git is a version control system. Think of it as a save button with a full history: every time you record your work, Git remembers exactly what changed. If something breaks, you can go back to any earlier version. It runs on your own computer and does not need the internet.

What is GitHub

GitHub is a website where you store your Git projects online. It does three big things for you:

• Backup - your code is safe even if your laptop dies.
• Collaboration - many people can work on the same project in an organized way.
• Portfolio - employers look at your GitHub to see what you have built.

The commands to start with

You only need a handful of commands for daily work:

• git init - start tracking a project.
• git add and git commit - save a snapshot of your changes.
• git push and git pull - send your work to GitHub and bring down updates.
• git branch - work on a new feature without touching the main version.

How to practice

Create a free GitHub account and put even your smallest projects there. Commit often, with short messages that describe what you changed. Within a week the workflow becomes second nature, and you will have a public profile to show.

Where it fits in your learning

Git is not a separate career - it is a skill you use alongside everything else. Whether you are learning web development, Python or Java, you will use Git from your first project. In our courses you build real projects and store them on GitHub, so by the end you have both the skills and a portfolio.
