Git & GitHub

Git version control & GitHub collaboration — branching, merging, pull requests, GitHub Actions, CI/CD workflows, and team collaboration patterns.

Welcome to the complete Git & GitHub course — your practical guide to mastering version control and collaborative software development. Whether you are a solo developer managing your projects or part of a large team building production software, Git and GitHub are essential tools that every developer must know.

Course Overview

Git is the most widely used distributed version control system in the world, and GitHub is the largest platform for hosting and collaborating on Git repositories. Together, they form the backbone of modern software development workflows — from individual projects to enterprise-scale applications maintained by thousands of contributors.

This course teaches you Git from the ground up. You'll understand how version control works internally (the object model, refs, and the staging area), master everyday commands, learn branching and merging strategies used by professional teams, and become proficient in GitHub's collaboration features including pull requests, code reviews, issues, and GitHub Actions for CI/CD. By the end, you'll be comfortable contributing to open source projects and managing complex team workflows.

What You Will Learn

By completing this course, you will be able to:

Understand version control concepts — why VCS matters, centralized vs distributed systems, Git's architecture
Set up and configure Git — installation, global configuration, SSH keys, and GPG signing
Master core Git commands — init, add, commit, status, log, diff, and the staging area workflow
Work with branches effectively — create, switch, merge, rebase, delete, and resolve merge conflicts
Use remote repositories — clone, push, pull, fetch, upstream tracking, and managing multiple remotes
Collaborate on GitHub — forking, pull requests, code reviews, issues, labels, and project boards
Apply professional workflows — Git Flow, GitHub Flow, trunk-based development, and release management
Undo and recover changes — reset, revert, stash, cherry-pick, reflog, and recovering lost commits
Automate with GitHub Actions — CI/CD pipelines, automated testing, deployment workflows, and custom actions
Contribute to open source — finding projects, understanding contribution guidelines, and submitting quality PRs

Prerequisites

Before starting this course, you should have:

Basic command line skills — navigating directories, creating files, and running commands in terminal
Any programming experience — familiarity with writing and saving code files (any language)
A GitHub account — free to create at github.com
A computer with Git installed (we guide you through installation)

No prior Git experience is needed. We start from the very first git init.
