If you're new to software development, you have probably heard the terms Git and GitHub many times. They are often mentioned together, so it is easy to assume that Git and GitHub are the same thing.
They are not.
Git is a version control system, while GitHub is a platform for hosting Git repositories and collaborating on software projects.
Understanding this difference is important because Git is one of the fundamental tools developers use to manage code. At the same time, GitHub provides an online environment where developers can store, share, review, and collaborate on that code.
In this guide, we'll look at Git and GitHub in simple terms, see how they work together, and walk through a basic example.
What Is Git?
Git is a distributed version control system used to track changes in files, especially source code.
Imagine you're working on a website. You make several changes over a few days. One change breaks something, and now you want to return to an earlier working version.
Without version control, you might have to manually maintain multiple copies of your project.
Git solves this problem by keeping a history of your changes.
You can create a commit whenever you reach a useful point in your project:
git add.
git commit -m "Add homepage"
Git records that change, allowing you to review the project's history and move between different versions when necessary.
Why Do Developers Use Git?
Git becomes particularly useful when a project contains many files or multiple developers are working on the same codebase.
Some common reasons developers use Git include:
Tracking changes
Maintaining project history
Creating separate branches
Experimenting with new features
Collaborating with other developers
Reviewing changes before merging them
Returning to an earlier version when something goes wrong
Git can also work locally on your computer, so you don't need an internet connection for many everyday Git operations.
What Is GitHub?
GitHub is a web-based platform built around Git repositories.
A Git repository is a project managed by Git. It contains the project's files along with information about its version history.
GitHub allows developers to store repositories online and collaborate with other people.
For example, a developer can create a repository for a web project and push their local Git repository to GitHub.
Once the project is on GitHub, team members can access it, review changes, create issues, and contribute to the project.
GitHub also provides features such as:
Pull requests
Issues
Code reviews
Repository management
Team collaboration
Public and private repositories
Git vs GitHub: The Simple Difference
The easiest way to remember the difference is:
Git manages your code history. GitHub helps you store and collaborate on that code online.
Think of Git as the tool that manages the history of your project, while GitHub is an online platform where that project can be hosted and shared.
A Simple Real-World Example
Suppose you're building a portfolio website.
You create a folder called:
my-portfolio
You initialize Git inside that folder:
git init
Git now starts tracking the project.
You create your first webpage and save your work:
git add.
git commit -m "Create portfolio homepage"
Later, you add a contact page:
git add.
git commit -m "Add contact page"
Now Git has a history containing your previous changes.
If you also want to store the project online and share it with teammates, you can connect the local repository to a GitHub repository and push your commits.
A simplified workflow looks like this:
Your Computer

Git

Collaboration
This is how Git and GitHub commonly work together.
Common Git Commands Beginners Should Know
You don't need to memorize dozens of commands when you're starting. Begin with the basics.
- git init
Creates a new Git repository in your project directory.
git init
- git status
Shows the current state of your working directory.
git status
It can help you see which files have been modified, added, or are waiting to be committed.
- git add
Adds changes to the staging area.
git add.
You can also add a specific file:
git add index.html
- git commit
Records staged changes in the repository history.
git commit -m "Update homepage"
A good commit message briefly describes what you changed.
- git clone
Downloads an existing repository to your computer.
git clone
This is useful when you want to work on an existing project.
- git pull
Gets changes from a remote repository and integrates them into your local project.
git pull
- git push
Sends your local commits to a remote repository.
git push
When working with GitHub, git push is commonly used to upload your committed changes to the remote repository.
What Is a Git Repository?
A repository, often called a repo, is a project managed using Git.
It contains your project files and Git's information about the project's history.
A repository can exist locally on your computer.
It can also be hosted remotely on a platform such as GitHub.
For example:
Local Repository
↕
Git
↕
Remote Repository
↓
GitHub
This setup makes it possible for developers to work locally while sharing their project through an online repository.
What Are Git Branches?
Branches are another important Git concept.
Suppose your main project is working correctly, but you want to experiment with a new login feature.
Instead of changing the main code directly, you can create a separate branch:
git branch login-feature
git switch login-feature
You can then develop the feature independently.
Once the feature is ready, it can be merged into the main branch.
Branches are especially useful when several developers are working on different features at the same time.
Difference between GIT and GITHUB
What Is a Pull Request on GitHub?
A pull request, commonly called a PR, is a GitHub feature used to propose changes to a repository.
For example, imagine that you create a new feature on your branch.
Instead of immediately changing the main branch, you can push your branch to GitHub and open a pull request.
Other developers can then:
Review your changes
Leave comments
Suggest improvements
Discuss the implementation
Approve the changes
After the review process, the changes can be merged into the main project.
This makes GitHub particularly useful for team-based development.
Do You Need GitHub to Use Git?
No.
You can use Git without GitHub.
Git is software that can be installed on your computer and used to manage a project locally.
GitHub is optional if you only need local version control.
However, GitHub becomes very useful when you want to:
Back up a repository online
Share your code
Collaborate with developers
Contribute to open-source projects
Showcase projects in your developer portfolio
Do You Need Git to Use GitHub?
GitHub is designed around Git repositories, and Git is the underlying version-control technology used by GitHub repositories.
You can interact with GitHub through its web interface and other tools, but understanding basic Git concepts and commands is extremely useful for developers.
Git and GitHub in a Development Workflow
A typical beginner workflow might look like this:
Step 1: Create a project
Start a new project on your computer.
Step 2: Initialize Git
git init
Step 3: Make changes
Write code and add features.
Step 4: Check your changes
git status
Step 5: Stage your files
git add.
Step 6: Create a commit
git commit -m "Add new feature"
Step 7: Push the project to GitHub
After connecting your local repository to a GitHub repository, you can push your commits:
git push
Step 8: Collaborate
Your team can review the project, create branches, open pull requests, and discuss changes through GitHub.
This workflow may look complicated initially, but it becomes natural with regular practice.
Final Thoughts
Git and GitHub are closely connected, but they solve different problems.
Git is responsible for version control and tracking changes in your project. GitHub provides an online platform for hosting Git repositories and collaborating with other developers.
Once you understand this distinction, many Git and GitHub concepts become easier to understand.
If you're learning web development or programming, Git is a valuable skill to add to your toolkit. Start with a small project, create commits, experiment with branches, and gradually learn how GitHub can help you collaborate and share your work.
The best way to learn Git isn't by memorizing every command. Create a project, make changes, break something, fix it, and use Git to understand what happened.
