Here’s a beginner-friendly guide to help you understand:
🧰 How to Use Git and GitHub for Version Control
Whether you’re building a website, mobile app, or working with a team, version control is essential to keep track of changes and collaborate smoothly. That’s where Git and GitHub come in.
🔄 What Is Version Control?
Version control lets you:
- Track changes in your code over time
- Revert to previous versions if something breaks
- Work with others without overwriting each other’s work
🐙 What Is Git?
Git is a local version control system. It tracks changes in your project on your computer.
☁️ What Is GitHub?
GitHub is a remote hosting platform for Git repositories. It allows you to:
- Back up your code online
- Share projects publicly or privately
- Collaborate with others (pull requests, issues, etc.)
- Show off your portfolio
✅ What You Need
- Install Git
- Create a free GitHub account
🔧 Basic Git Workflow
1. Create a Project Folder
mkdir my-project
cd my-project
2. Initialize Git
git init
This creates a .git folder to track your changes.
3. Track Files
Create a file like index.html, then:
git add index.html
Or add everything:
git add .
4. Commit Your Changes
git commit -m "Initial commit"
This saves a snapshot of your code.
5. Connect to GitHub
First, create a new repo on GitHub (don’t add README).
Then, link your local repo:
git remote add origin https://github.com/yourusername/my-project.git
Push your code to GitHub:
git push -u origin main
(If your branch is master, use master instead of main.)
🔁 Basic Git Commands Cheat Sheet
| Command | What It Does |
|---|---|
git init |
Start tracking a new project |
git status |
See changes and staging info |
git add . |
Stage all changes |
git commit -m "message" |
Save a version |
git log |
View commit history |
git remote add origin [url] |
Connect to GitHub |
git push / git pull |
Sync with GitHub |
git clone [repo-url] |
Copy someone’s GitHub repo |
git branch |
View branches |
git checkout -b new-branch |
Create & switch to a new branch |
git merge branch-name |
Combine another branch into current |
🌿 Branching Example
Branching helps you experiment without affecting the main code.
git checkout -b new-feature
Work on your feature, then:
git add .
git commit -m "Add new feature"
git checkout main
git merge new-feature
👥 Collaboration: Pull Requests
On GitHub, when someone makes a change, they can open a Pull Request (PR) to propose it.
Steps:
- Fork a repo
- Make changes in a new branch
- Push to your fork
- Open a Pull Request on GitHub
- Discuss and merge
🔐 .gitignore File
Create a .gitignore file to prevent committing unwanted files:
node_modules/
.env
*.log
🧠 Tips for Beginners
- Make frequent commits with meaningful messages
- Use branches to test features
- Push your projects to GitHub to build a portfolio
- Use GitHub Issues to manage tasks
