How to Use GitHub? A Complete Beginner Guide

If you are new to programming or just started at a tech company, someone probably told you: "Put your code on GitHub." You open github.com, see a wall of English and code, and have no idea where to start.

This article is for people who have never used GitHub. No commands, no branches -- just a clear explanation of what GitHub is, what it can do, and what each button is for.

What Is GitHub, Really

One sentence: GitHub is the world largest code hosting platform and developer community.

Think of it as a "cloud drive plus social network" for programmers.

Cloud drive: your code lives in the cloud. If your computer dies or your hard drive fails, your code is safe. Switch to a new computer, download the code, and keep working.

Social network: you can see other people projects, download them to learn from, or contribute to them. Others can see your projects, suggest improvements, or use them directly.

As of 2026, GitHub has over 100 million developers and hundreds of millions of projects. Almost every famous open-source project is on it: Linux, Python, React, Vue, ChatGPT clients -- if you can think of it, it is probably on GitHub.

Registration and Interface

Go to github.com, click Sign up, and register with your email. Choose your username carefully -- it becomes your GitHub homepage URL.

After logging in, you see the homepage. The left side shows updates from projects you follow, the middle shows recommendations, and the right side shows trending projects. As a beginner, do not worry about any of this. Just get familiar with the page structure first.

The top navigation bar has several important elements:

• Search bar: search for repositories, users, and code
• Pull Requests: your PRs and PRs you're reviewing
• Issues: Issues you've created or that are assigned to you
• Marketplace: tools and apps that extend GitHub
• Explore: discover trending projects and topics

Project Page Structure

Open any project and you will notice all project pages have almost the same layout. Understand one, and you understand them all.

At the top is the project name in the format "username/repo name". To the right of the repo name are three buttons -- these are the three most important features on all of GitHub.

Watch means follow. Click it and you get notified when the project has updates. Project authors usually recommend you watch their own projects.

Fork means copy. Click it and the entire project is copied to your account. You can do whatever you want with your copy without affecting the original. If you want to contribute to an open-source project, forking is always the first step.

Star means like and bookmark. It is essentially clicking "useful" on a project. Star count is the most intuitive quality signal -- a project with tens of thousands of stars is almost certainly good. Many developers put their star count on their resume because it represents genuine recognition from developers worldwide. It carries far more weight than writing "proficient in XX" on a resume.

Across the top is a row of tabs.

Code shows all the project code files. This is the default tab. You can browse the file tree, search within the project, and view file history.

Issues is the discussion area. Found a bug? Want to suggest a feature? Have a question? Post it here. Think of it as the project suggestion box.

Pull Requests are change suggestions from other people. Someone forks a project, makes improvements, and wants to merge those changes back to the original. That is a Pull Request, or PR. The project author reviews it and adopts it if everything looks good.

Actions, Projects, and Wiki are advanced features. Actions automates CI/CD pipelines. Projects provides kanban-style project management. Wiki offers a documentation system integrated with the repository.

Below the tabs is the file tree and README. README is the project description. Almost every project has one. A good README tells you what the project does, how to install it, and how to use it. Always read the README before touching anything else.

As a User: How to Find Projects and Use Them

Many people open GitHub to use other people projects. Instead of writing a login component from scratch, you find an existing open-source one.

There are four efficient ways to find projects.

Search directly using the top search bar. Search "AICHAT" or "python chatbot", then filter by star count in the results. More stars means more reliable.

Check GitHub Trending. The right side of the homepage or the Explore page shows Trending -- what projects are hottest globally right now.

Use the Topics page. GitHub tags every project with labels like Python, chatbot, or LLM. Filter by topic on the Topics page to quickly find quality projects in a specific domain.

Fourth, look for Awesome projects. Awesome lists are community-curated directories like awesome-python or awesome-LLM. They organize the best projects in a category, saving you months of searching.

Found a project and wondering if it is worth using? Check four signals.

Star count: 1,000 or more is generally reliable; 10,000 or more is likely a domain leader.

Recent commit: if it has not been updated in over a year, the project is effectively dead. Do not use it.

Open issues status: if issues are being replied to and resolved, the author is still maintaining the project.

README quality: if a project does not even have a decent description, do not expect a good experience.

Decided to use it? How do you download it?

The simplest way is to click the green Code button and choose Download ZIP. Extract it and you can see the code.

The standard programmer approach is git clone. If you have Git installed:

git clone https://github.com/username/repo-name.git

The project downloads to your computer.

How to run it? 99% of projects put the run instructions in the README under Installation or Quick Start. Just follow along.

A newer approach for 2026: paste the project URL into an AI and have it clone, install dependencies, fix errors, and run the project for you. Ten times faster than reading documentation.

As a Creator: How to Upload Your Own Project

If you want to put your code on GitHub for others to see or collaborate on.

Step one, create a repository on GitHub. Click New Repository in the top right, name it, and choose Public (visible to everyone) or Private (only you can see).

Step two, push your local code. If you already have a local project:

git init
git add .
git commit -m "first commit"
git remote add origin https://github.com/your-username/repo-name.git
git push -u origin main

Step three, write a README. This is your project storefront. A good README should include:

A first line that clearly states what the project does and what problem it solves. Then a screenshot or GIF -- text-only READMEs have extremely low conversion. Then installation instructions that anyone can follow in five minutes. If you can manage it, make it bilingual in Chinese and English. Stars from overseas users carry more weight.

Step four, choose a LICENSE. Beginners should pick MIT -- it is the most permissive, allowing anyone to use, modify, and distribute your code. Without a LICENSE, all rights are reserved by default, and others cannot legally use your project.

Essential GitHub Workflows for Beginners

Beyond the basics, here are a few workflows that will help you get more out of GitHub:

Branching lets you work on features without affecting the main code. Create a branch with git checkout -b feature-name, make your changes, and merge back when ready. This is the backbone of collaborative development.

Pull Requests aren't just for contributing to others. Even on your own projects, creating a PR for your changes gives you a chance to review your own diff before merging. It is a simple form of self-review that catches many mistakes.

GitHub Actions can automatically run tests, build your project, or deploy it when you push code. The starter workflows available in the Actions tab make it easy to set up continuous integration in minutes.

GitHub Pages hosts static websites directly from your repository. If you want a simple portfolio or project documentation site, this is the easiest way to get it online for free.

About Star Count

Star count is not just a number -- it has real value in the programming world.

Many companies check your GitHub profile when hiring. If a personal project has 500 to 800 stars, many HR departments will call you directly, skipping resume screening entirely. A resume is self-promotion; stars are genuine endorsement from developers worldwide.

How do you get stars? Three words: make something useful.

If the project is genuinely useful, has a clear README, and includes screenshots, people will star it naturally. You can also submit your project to the relevant Awesome list for more exposure.

Wrapping Up

GitHub comes down to three things: storing code, finding projects, and showcasing yourself.

Store code with git push. Find projects with search and trending. Showcase yourself with a good README and consistent maintenance.

You do not need to learn everything at once. Register an account, open a few projects to look at the page structure, star something interesting -- and you have already taken your first step into GitHub.
