What is Git?

Learn what Git is, why it exists, and how it helps developers track changes and work safely on projects.

Git is a distributed version control system used to track changes in source code over time.

It allows developers to:

• Save versions of their work

• Go back to previous states

• Work on the same project without overwriting each other

Why Git exists?

Before Git, teams shared code manually, which caused:

• Lost work

• Broken files

• No history

Git solves this by keeping a full history of changes and managing collaboration safely.

How Git works?

Git works by:

• Taking snapshots of your project

• Storing them as commits

• Letting you move between versions

Every developer has a complete copy of the project history.

Git tracks project history using commits and branches.

Git is not GitHub

• Git is a tool.

• GitHub is a platform built on top of Git.

You can use Git without GitHub, but GitHub makes collaboration easier.

When you use Git?

You use Git when you:

• Build applications

• Work in teams

• Experiment without breaking code

• Want a safety net for your changes

In modern development, Git is a core skill, not an optional one.
