Introduction

Git is a tool for tracking changes in your code, while GitHub is a platform to share your Git repositories online. Together, they help you manage your projects, work with others, and keep your code safe. These tools are essential for every developer today.

Why Use Git and GitHub?

Git helps you save different versions of your work and go back if you make a mistake. GitHub allows you to share your code, contribute to other projects, and showcase your work to employers or other developers. It's like a social network for code.

Roadmap to Learn Git & GitHub

• Understand version control: Learn why we need it and what problems it solves.
• Install Git: Set it up on your computer.
• Basic commands: git init, git add, git commit, git status.
• Working with branches: Create, merge, and manage different features safely.
• Remote repositories: Push and pull code using GitHub.
• Collaboration: Use pull requests and code reviews.
• Advanced topics: Rebasing, resolving conflicts, and using Git workflows.

History

Git was created in 2005 by Linus Torvalds to manage the Linux kernel code. GitHub launched in 2008 and quickly became the biggest hosting service for Git repositories. Today, millions of developers and companies use Git and GitHub to manage and share code worldwide.

Important Concepts

• Repository: A project folder tracked by Git.
• Commit: A snapshot of your changes.
• Branch: A separate line of development to add new features safely.
• Merge: Combine changes from one branch to another.
• Clone: Copy a repository from GitHub to your computer.
• Pull & Push: Download (pull) or upload (push) changes to GitHub.
• Fork: Make your own copy of someone’s repository to customize it.
• Pull request: Suggest changes to a project and ask for review.

Common Beginner Mistakes

• Not committing often enough or with clear messages.
• Making changes directly on the main branch instead of using branches.
• Forgetting to pull latest changes before pushing code.
• Being afraid of merge conflicts instead of learning how to resolve them.

"The best way to learn Git is by using it daily. Don't be afraid to experiment and break things!"
