Version control with Git and GitHub

Version Control

Version control is a system that records every change made to your code. It lets you track project history, roll back to previous versions, and collaborate without chaos.

Git

Git is a command-line-based version control tool used in nearly all modern software projects.

Key Git features:

• Commit: saves a snapshot of your code


• Branch: lets you create separate workspaces for new features or experiments


• Merge: brings changes together from different branches

Github

Git works locally, GitHub works online. GitHub is a platform for hosting your Git repositories, enabling collaboration, pull requests, and cloud-based code sharing.

Why GitHub matters:

• Store and share your code online


• Collaborate through pull requests and code review


• Integrates with tools like CI/CD, issue tracking, etc.

Git + GitHub: Better Together

Git helps you manage changes locally. GitHub helps you work with others and keep your project alive in the cloud.
