Introduction
In modern software development, keeping track of code changes is essential. Git provides a robust way to manage versions of your projects, while GitHub adds collaboration, project management, and sharing capabilities.
Think of Git as a time machine for your code and GitHub as the social network for developers.
⚙️ Why Git & GitHub Matter
Git & GitHub provide:
✅ Version Control – track changes and revert mistakes ⚡ Collaboration – work with teammates seamlessly 🧩 Branching & Merging – experiment safely without breaking main code 📦 Project Management – issues, pull requests, and code reviews 🚀 Open Source & Community – share projects globally
🧱 Core Concepts Concept Role Repository (Repo) Stores project files and history Commit Record changes with a message Branch Independent lines of development Merge Combine changes from different branches Pull Request (PR) Propose changes for review Clone Copy a repository locally Push & Pull Upload/download changes to/from remote GitHub Actions Automate workflows and CI/CD 🛠 How Git & GitHub Work
Initialize a repository locally (git init)
Track changes and commit (git add, git commit)
Create branches for new features (git branch)
Push to GitHub to share (git push)
Collaborate via pull requests and code reviews
Merge approved changes into main branch
Update local repository with remote changes (git pull)
This workflow ensures code is safe, organized, and collaborative.
