Master Git & GitHub: A Complete Self‑Study Roadmap for Developers

What are Git and GitHub?

Git is a distributed version control system that records every change, allows browsing history, and enables reverting to previous versions. Each developer keeps a full local repository that can be synchronized with others.

GitHub is a cloud‑based code‑hosting platform that stores Git repositories, supports sharing, collaboration, and discovery of open‑source projects.

Why use Git/GitHub?

Created by Linus Torvalds for the Linux kernel, Git coordinates many contributors, prevents duplicate work, preserves history, and simplifies merging changes. GitHub provides a public, widely adopted space where anyone can explore, fork, and contribute to projects, making it a valuable skill for developers.

When to start learning?

After learning at least one programming language.

Before beginning personal projects, so the project can be managed on GitHub from the start.

Learning roadmap

1. Git Basics

Goal: Understand core concepts (working tree, index, local and remote repositories) and complete a full commit workflow.

Key commands: git init, git clone, git add, git commit, git push, git fetch, git pull, git status, git log.

Practice: Follow a beginner tutorial (e.g., “Monkey Can Understand Git”) and use the interactive game Learning Git Branching to master branching.

2. GitHub Basics

Goal: Perform basic GitHub operations, search and download code, and understand the GitHub Flow.

Key topics:

Creating repositories, forking, cloning, starring, watching.

Uploading local code, editing profile.

GitHub Flow: fork → branch → commit → pull request → code review → merge → delete branch.

Issues, pull requests, basic project management.

3. Git Advanced

Goal: Master advanced Git commands and conflict‑resolution techniques.

Key topics:

Tags ( git tag), checkout, stash, clean, rebase, reset, revert.

Search ( git grep), diff, blame, reflog, interactive mode.

Hooks (e.g., pre‑commit), .gitignore, cherry‑pick, worktree, Git Flow, monorepo concepts.

Comparison with other VCS.

4. GitHub Advanced

Goal: Leverage extended GitHub features to improve development efficiency and project management.

Key topics:

SSH configuration for secure cloning.

GitHub shortcuts, Apps, and code security.

Codespaces, Discussions, Pull Requests.

Organizations, Issues, Projects, Insights, contributor management, licensing.

GitHub Pages, Gitpod, Actions, Packages, Webhooks.

Self‑hosted Git servers (GitLab, Gogs).

Interview points

Git questions appear in a small fraction of interviews, typically covering basic concepts, common commands, branching, tags, and conflict resolution.

Difference between Git and GitHub. Purpose of git init , git clone , git commit , git push . How to resolve merge conflicts. Understanding of branches and tags.
