What Is Git?
Git is a distributed version control system that helps developers track changes in their code. It allows multiple people to work on the same project simultaneously without overwriting each other’s changes. With features like branching, merging, and commit history, Git ensures a smooth development workflow.
Key Features of Git:
- Version Tracking: Keeps a history of changes.
- Branching and Merging: Enables feature development in isolation.
- Distributed Architecture: Work offline and sync changes later.
What Is GitHub?
GitHub is a cloud-based platform built on top of Git. It offers tools for hosting repositories, collaborating with teams, and managing projects efficiently. GitHub also powers the open-source community, allowing developers worldwide to share and contribute to projects.
Key Features of GitHub:
- Repository Hosting: Store your code in the cloud.
- Collaboration: Share your work with others using pull requests and issues.
- Continuous Integration: Automate testing and deployment.
- Community: Discover open-source projects and contribute.
Git vs. GitHub: What’s the Difference?
While Git is a version control system, GitHub is a platform for hosting and sharing Git repositories. Think of Git as the engine, and GitHub as the car that uses the engine to reach its destination.
| Feature | Git | GitHub |
|---|---|---|
| Purpose | Version control | Repository hosting & collaboration |
| Offline Capability | Yes | No |
| Collaboration | Local with Git commands | Cloud-based with GitHub tools |
How Git and GitHub Work Together
- Create a Local Repository: Use Git to track your project locally.
- Push to GitHub: Upload your repository to GitHub to collaborate with others.
- Contribute to Projects: Use GitHub’s tools to work on existing repositories.
Getting Started
Step 1: Install Git
Download Git from git-scm.com and follow the setup instructions.
Step 2: Create a GitHub Account
Sign up at github.com to host your repositories.
Step 3: Connect Git to GitHub
Set up your credentials:
git config --global user.name "Your Name"
git config --global user.email "[email protected]" Step 4: Push a Local Repository to GitHub
- Initialize a repository:
git init - Add a remote origin:
git remote add origin https://github.com/your-username/repo-name.git - Push your code:
git push -u origin main
Why Learn Git and GitHub?
- Version Control: Track your changes and avoid data loss.
