Git Explained: Workflow, Commands & Tools
How Git Works: A Beginner's Guide to Version Control
Git is one of the most powerful tools in a developer's toolkit — yet many beginners find it confusing at first. This guide breaks down exactly how Git works, what its three local storage areas do, and the essential commands you need to get started.
What Is Git?
Git is a distributed version control system that tracks changes in your code over time. It lets you collaborate with teammates, experiment safely, and roll back mistakes without losing your work.
Created by Linus Torvalds in 2005 to manage the Linux kernel, Git has since become the industry standard for source code management used by millions of developers worldwide.
Why Use Git?
- Track every change made to your codebase
- Collaborate seamlessly with other developers on different parts of a project
- Revert to previous versions if something breaks
- Work offline — Git stores everything locally, not just in the cloud
How Git's Three Local Storage Areas Work
When people say Git is "distributed," they often imagine just two locations: your computer and a remote server. But locally, Git actually uses three distinct storage areas.
1. Working Directory
This is your active workspace — where you write and edit files.
Any changes made here are untracked by default. If you don't tell Git about them, they won't be saved. Think of this as your draft space.
⤷ Files here are not backed up by Git until you explicitly add them.
2. Staging Area
When you run git add, your files move from the Working Directory into the
Staging Area.
Git now starts tracking those changes. They're stored inside the .git directory. However, if you make
further edits after staging, Git won't automatically know — you'll need to run git add again.
⤷ Think of staging as preparing a package before you seal and send it.
3. Local Repository
Running git commit moves your staged changes into the Local Repository — permanently
recorded in the .git directory.
After committing, your staging area clears. You can review your full commit history anytime with
git log.
⤷ This is your project's complete, versioned history — all stored on your machine.

⤷ Git Workflow at a Glance
Working Directory → (git add) → Staging Area → (git commit) → Local Repository → (git push) → Remote RepoUnderstanding this flow is the key to mastering Git. Once it clicks, everything else — branching, merging, pull requests — becomes much easier.
Learn how Git works — from its three local storage areas to essential commands like git add, commit, and push. A beginner-friendly guide to mastering version control.
Git is a distributed version control system that tracks code changes across three local storage areas: the Working
Directory, Staging Area, and Local Repository. Developers use commands like git add,
git commit, and git push to move code through each stage and collaborate efficiently.
⤷ FAQ
Q1: What is Git and why is it used? Git is a distributed version control system used to track changes in source code. It helps developers collaborate on projects, maintain a full history of edits, and revert mistakes. Created in 2005 by Linus Torvalds, it's now the world's most widely used version control tool.
Q2: What are the three storage areas in Git? Git uses three local storage areas: the Working
Directory (where you edit files), the Staging Area (where changes are prepared with git add), and the
Local Repository (where commits are permanently saved with git commit). Each serves a distinct role in
the Git workflow.
Q3: What is the difference between git pull and git push? git pull downloads the
latest changes from a remote repository to your local machine, keeping your code up to date.
git push does the opposite — it uploads your committed local changes to the remote repository so others
can access them.
Q4: What are the most important Git commands for beginners? The most essential Git commands are:
git init (create a repo), git add (stage changes), git commit (save changes),
git push (upload to remote), git pull (download updates), git status (check
file states), and git diff (compare changes).
Q5: Are there GUI tools that make Git easier to use? Yes! Popular Git GUI tools include GitHub Desktop, GitKraken, SourceTree, TortoiseGit, SmartGit, and Tower. These tools provide a visual interface for managing branches, commits, and merges — making Git much more accessible for beginners and non-technical team members.
