Introduction to Git & GitHub

Welcome to the complete guide to Git and GitHub! This documentation will take you from beginner to proficient in version control and collaborative development.

Quick Navigation


What is Git?

Git is a distributed version control system (VCS) that revolutionizes how developers track and manage code changes.

Core Capabilities

  • Version Tracking: Save snapshots of your project at different points in time
  • Change History: See exactly what changed, when, and by whom
  • Branching: Work on multiple features simultaneously without conflicts
  • Collaboration: Multiple developers can work on the same project seamlessly
  • Backup & Recovery: Never lose work with distributed backups

💡 Think of Git as a "time machine + collaboration tool" for your code


What is GitHub?

GitHub is a cloud-based platform that hosts Git repositories and adds powerful collaboration features.

Key Features

  • Repository Hosting: Store your code in the cloud
  • Collaboration Tools: Pull Requests, Issues, Project Boards
  • Code Review: Review and discuss changes before merging
  • CI/CD: Automate testing and deployment with GitHub Actions
  • Community: Contribute to millions of open-source projects
  • Documentation: Wikis, GitHub Pages for project websites
