What is GitHub?
GitHub is a cloud-based platform that allows developers to store, manage, and collaborate on code. It builds on Git, a distributed version control system created by Linus Torvalds in 2005, by adding a user-friendly interface and powerful collaboration tools. GitHub was founded in 2008 and quickly became the world’s largest host of source code. In 2018, it was acquired by Microsoft, which has continued to expand its features and integration with developer tools.
Today, GitHub hosts millions of projects, ranging from small personal experiments to massive open-source initiatives like the Linux kernel, React, and Visual Studio Code. By combining Git’s version control with social features such as pull requests, issues, and discussions, GitHub makes it easy for developers to work together across the globe.
Why Learn GitHub?
GitHub is used by millions of developers and organizations to host code, track changes, and collaborate on projects. Learning GitHub gives you access to open-source communities, professional workflows, and tools that are essential in modern software development.
For students and professionals alike, GitHub is more than just a coding platform—it’s a portfolio. Employers often look at GitHub profiles to evaluate a candidate’s skills, contributions, and coding style. By learning GitHub, you not only gain technical expertise but also build a public record of your work that can help you stand out in job applications.
GitHub also supports publishing through GitHub Pages, allowing you to turn repositories into live websites. This means you can showcase projects, documentation, or even personal blogs directly from your GitHub account.
About This Tutorial
This site is designed for beginners who want to learn GitHub from scratch. Whether you're a student, someone exploring software development, or just enjoy building projects, you'll find step-by-step instructions to help you get started.
The tutorial is organized into clear sections: account setup, interface navigation, repository creation, file management, collaboration, and troubleshooting. Each page builds on the previous one, so by following the sequence you’ll gradually develop confidence in using GitHub’s features.
Who This Tutorial Is For
This guide is for beginners with little to no experience using GitHub. You don’t need to buy any subscriptions. GitHub is free to use. All you need is a web browser and an internet connection to follow along.
Even if you’re not a programmer, GitHub can be useful. Writers, designers, and project managers use GitHub to collaborate on documentation, track tasks, and organize workflows. If you’re curious about open-source communities or want to learn how modern teams collaborate online, this tutorial is for you.
Learning Objectives
By the end of this tutorial, you will be able to:
- Create and manage repositories: the foundation of organizing your projects.
- Customize your GitHub account: make your profile stand out to collaborators and employers.
- Upload and organize files: keep your codebase clean and accessible.
- Use GitHub Codespaces: develop directly in the cloud without local setup.
- Track changes using version control: understand commits, branches, and merges.
- Collaborate using forks, pull requests, and issues: work effectively with teams and communities.
- Publish a website using GitHub Pages: share your projects with the world.
How to Use This Site
- Begin with the Account Setup page to create your GitHub account.
- Progress through each section to build your skills step by step.
- Practice by creating a test repository to experiment safely.
- Refer to the Glossary / FAQ for definitions and the Troubleshooting page for help.
Before You Begin
Make sure you have a valid email address. You’ll be creating a GitHub account in the next section, so have your preferred username and a secure password ready. Consider enabling two-factor authentication for added security. This ensures that even if someone learns your password, they cannot access your account without a secondary verification step.
Think about how you want to present yourself on GitHub. Your username will become part of your public identity, so choose something professional or memorable. Many developers use their real names, while others prefer creative handles. Either way, consistency across platforms (GitHub, LinkedIn, Twitter) can help build your personal brand.
