GitHub 101 – A Beginner’s Guide to Version Control and Collaboration

GitHub, a web-based platform built around the Git version control system, is an essential tool for developers and teams working on software projects. Whether you’re a seasoned developer or just starting, this GitHub 101 guide will introduce you to the basics, helping you understand the key concepts and workflows.

1. Understanding Version Control:

What is Version Control? Version control is a system that records changes to a file or set of files over time. It allows you to track and manage changes, collaborate with others, and revert to previous states if needed.

Git Basics: Git is a distributed version control system that helps manage and track changes efficiently. It operates locally on your machine, allowing for faster operations and offline work.

2. GitHub Basics:

What is GitHub? GitHub is a hosting service for Git repositories. It provides a web-based interface, collaboration tools, and additional features to enhance the Git experience.

Creating a GitHub Account:

1. Go to GitHub.
2. Click on “Sign Up” and follow the account creation process.

Creating a Repository:

1. Click on the “+” sign in the top right corner.
2. Select “New Repository.”
3. Name your repository and provide a brief description.
4. Initialize with a README if you want to start with a README file.

3. Working with Repositories:

Cloning a Repository: To work on a project locally, you’ll clone the repository to your machine:

git clone https://github.com/username/repository.git

Making Changes:

1. Make changes to files in your local repository.
2. Use git add to stage changes and git commit to save them.

Pushing Changes: Upload your local changes to GitHub:

git push origin main

4. Collaborating on GitHub:

Forking:

1. Fork a repository on GitHub.
2. Clone your forked repository locally.
3. Make changes and push them to your fork.
4. Create a pull request to propose changes to the original repository.

Branching: Create a new branch to isolate changes and prevent conflicts:

git checkout -b feature-branch

5. GitHub Workflow:

git add .
git commit -m "Add feature"

5. Push Changes:

git push origin feature-branch

6. Open a Pull Request:
