Quick Answer

**Git is a distributed version control system that tracks changes to code files, enables multiple developers to collaborate on the same project, and maintains a complete history of every modification ever made.**

**Git** is the version control system used by virtually every software team in the world. Created by Linus Torvalds in 2005, it tracks every change made to every file in a project, who made the change, and when. If something breaks, you can revert to any previous state instantly.

## Why Git Matters

Without version control, collaboration is chaos. Two developers editing the same file would overwrite each other’s work. There would be no way to review changes before they go live, no way to trace when a bug was introduced, and no way to safely experiment with new features.

Git solves all of these problems. **Branching** lets developers work on features in isolation without affecting the main codebase. **Merging** combines completed features back into the main branch. **Pull requests** provide a structured review process where team members can review, comment on, and approve changes before they are merged.

## How Git Works in Practice

A typical development workflow using Git looks like this. A developer creates a **branch** from the main codebase. They make changes and **commit** them (save snapshots) as they work. When the feature is complete, they open a **pull request** on GitHub, GitLab, or Bitbucket. Team members review the code, suggest changes if needed, and approve it. The branch is **merged** into main, and the [CI/CD pipeline](https://app369.com/glossary/what-is-cicd/) automatically tests and deploys the updated code.
