Git & Github Mastery Roadmap 2025

Phase 1: Beginner

0–1 month

Understand what version control is & confidently use Git locally

Concepts

  1. 1. What is Version Control System (VCS)

Core Git Commands - Setup

  1. 1. git config — Configure user settings
  2. 2. git init — Create repository

Core Git Commands - Snapshot

  1. 1. git add — Stage changes
  2. 2. git commit — Record changes
  3. 3. git status — Check working directory status
  4. 4. git log — View commit history

Core Git Commands - View & Undo

  1. 1. git diff, git show, git blame — Compare & inspect changes
  2. 2. git restore, git reset, git revert — Undo mistakes safely

Practice Projects

  1. 1. Create a local Git repo
  2. 2. Track a text or code project with commits
  3. 3. Undo changes using git restore
  4. 4. View history with git log --oneline --graph
  5. 5. Edit and version-control a simple 'Notes' project
  6. 6. Write meaningful commit messages (feat:, fix:, docs: style)
Phase 1
Phase 2
Phase 2: Intermediate

1–2 months

Collaborate, branch effectively, and use GitHub professionally

Branching & Merging

  1. 1. Create & switch branches (git branch, git checkout -b)

  4. 4. Resolve merge conflicts manually

GitHub Essentials

  1. 1. Create remote repos
  2. 2. Push & pull (git remote, git push, git pull, git fetch)
  3. 3. Fork & clone other repos
  4. 4. Understand origin vs upstream

Collaboration Workflow

  1. 1. Feature branch workflow
  2. 2. Pull Request (PR) process
  3. 3. Code reviews & merging PRs
  4. 4. Protecting branches & enabling PR approvals

Authentication

  1. 1. SSH keys & Personal Access Tokens (PAT)
  2. 2. Connecting local Git with GitHub securely

Practice Projects

  1. 1. Collaborate on a small project with a friend
  2. 2. Create PRs, review & merge
  3. 3. Try rebasing your feature branch before merge
Phase 2
Phase 3
Phase 3: Advanced

2–3 months

Master advanced Git features & fix complex problems

Advanced Git Tools

  1. 1. Stash: git stash, git stash pop, git stash list
  2. 2. Cherry-pick: Move specific commits across branches
  3. 3. Reflog: Recover lost commits (git reflog)
  4. 4. Bisect: Debug commits that broke the code
  5. 5. Tags & Releases: git tag, annotated tags

Branching Strategies

  1. 1. GitFlow Workflow
  2. 2. Trunk-Based Development
  3. 3. Release & Hotfix Branches

Configuration Mastery

  1. 1. .gitignore, .gitattributes, .gitkeep
  2. 2. Git Hooks — pre-commit, post-merge
  3. 3. Global vs repo-level configs

Practice Projects

  1. 1. Create a GitFlow-based repo
  2. 2. Use stashing, cherry-pick, and revert
  3. 3. Write a pre-commit hook (lint check or code format check)
Phase 3
Phase 4
Phase 4: Professional GitHub Usage

3–4 months

Use GitHub like a pro for team & production workflows

GitHub Features

  1. 1. GitHub Actions (CI/CD basics)
  2. 2. GitHub Issues, Projects, and Milestones
  3. 3. GitHub Wiki & Discussions

Security & Governance

  1. 1. Managing collaborators, roles, teams
  2. 2. Repository settings: visibility, branch protection, signed commits
  3. 3. Secrets & environment variables in Actions
  4. 4. Dependabot alerts

Practice Projects
