What is Git? Complete Beginner Guide

Jun 27, 2026 by codewithhemu

Git is a distributed version control system (VCS) that helps developers track changes in their code, collaborate with teams, and maintain different versions of a project.

Simply put, Git acts like a time machine for your code. If you make a mistake or want to return to an older version, Git lets you do it easily.

Example Without Git

Imagine you are creating a Laravel project.

You save files like:

project_final.zip
project_final_new.zip
project_final_latest.zip
project_final_latest2.zip
project_final_final.zip

After a few days, you don’t know which file is the latest or what changes were made.

This becomes confusing.

Example With Git

With Git, your project remains in one folder.

LaravelProject/

Every time you complete a feature, you create a commit.

Commit 1
✔ Login Page Added

Commit 2
✔ Registration Added

Commit 3
✔ Forgot Password Added

Commit 4
✔ Dashboard Added

You can return to any previous version whenever needed.

What is Version Control?

Version Control is a system that records changes made to files over time.

It allows you to:

Track every change
Restore previous versions
Compare changes
Work with multiple developers
Prevent accidental data loss

Why Do We Need Git?

Suppose two developers are working on the same project.

Developer A

Added Login Feature

Developer B

Added Dashboard Feature

Git combines both changes without replacing one another.

Without Git, developers often overwrite each other’s work.

Features of Git

Fast

Git performs operations quickly because most data is stored locally.

Distributed

Every developer has a complete copy of the repository.

Even if the server goes down, your local repository still contains the full project history.

Secure

Git uses SHA hashing to ensure your project history remains safe and tamper-resistant.

Branching

Create separate branches to work on new features.

Example:

main
 ├── login-feature
 ├── payment-feature
 └── dashboard-feature

Merge

After testing, merge your feature branch back into the main branch.

History Tracking

Git records:

Who made the change
What changed
When it changed

Advantages of Git

Free and Open Source
Easy collaboration
Fast performance
Backup of project history
Undo mistakes easily
Supports multiple branches
Works offline
Industry standard

Real-Life Example

Imagine writing a book.

Version 1

Chapter 1

Version 2

Chapter 1
Chapter 2

Version 3

Chapter 1
Chapter 2
Chapter 3

Git saves each version.

If Chapter 3 contains mistakes, you can restore Version 2 instantly.

Companies That Use Git

Almost every software company uses Git.

Some examples include:

Google
Microsoft
Amazon
Meta
Netflix
Adobe
Spotify

Whether you’re working with Laravel, React, Python, Java, or Flutter, Git is an essential skill.
