Git Fundamentals

What is Git?

Git is a distributed version control system designed to handle everything from small to very large projects with speed and efficiency. It allows developers to track changes, collaborate, and manage source code effectively.

Key Concepts

Version Control

Version control is a system that records changes to files over time, enabling developers to:

• Recall specific versions
• Compare changes
• Revert to previous states
• Collaborate seamlessly

Git Architecture

Core Git Operations

Basic Git Workflow

1. Initialize or clone a repository
2. Make changes in working directory
3. Stage changes with git add
4. Commit changes with git commit
5. Push to remote repository

Why Use Git?

• Distributed development
• Branching and merging
• Traceability
• Collaboration
• Open-source friendly
