Why does every developer need Git and GitHub?
Two different tools that solve two different problems
Git is the version control system itself — it runs locally on your machine and tracks every change to your code, letting you experiment on branches, undo mistakes, and see exactly who changed what and when. It works the same whether you're solo or on a 200-person team.
GitHub is a hosting platform built around Git. It adds a remote home for your repositories plus the collaboration layer teams actually live in day to day: pull requests, code review, issues, project boards, and CI/CD through GitHub Actions.
Nearly every job posting that mentions "collaborative development" or "CI/CD" is really asking for comfort with both — clean local Git habits, and the GitHub workflows that turn individual commits into a reviewed, shipped product.
The Git and GitHub Roadmap
Work through these in order — local Git first, then the GitHub layer on top
Learn the Basics
What version control actually solves, and getting Git running on your machine.
What is a Repository
Turning a folder into something Git can actually track.
Intro and Git Commands
The daily loop: change files, stage them, and commit a snapshot.
Branching and Merging Basics
Working on features in isolation, then bringing the changes back together.
GitHub Essentials
Getting a profile and your first repositories set up on GitHub itself.
Remotes and Collaboration on GitHub
Connecting your local repo to GitHub, and working with other people's code.
Merge Strategies and Best Practices
The habits that keep a shared history readable instead of a tangled mess.
Working in a Team and GitHub Organizations
Scaling past a single repo into shared teams, boards, and planning.
Intermediate Git Topics
Parking work-in-progress and reading a history that isn't always a straight line.
Rewriting History, Tagging and Hooks
Editing commits that already happened, marking releases, and automating checks around them.
GitHub Workflow Automation
Managing repos from the command line, and running CI/CD on every push.
Advanced Git and the GitHub Ecosystem
The deep-cut tools and platform features you'll grow into over time.
GitHub Projects
Real repos to practise the exact workflows in this roadmap
Fork Your First Repo
GitHub's own practice repository, built specifically for forking, cloning, making a change, and opening your very first pull request.
Make Your First Contribution
A guided, beginner-friendly repo that walks you through cloning, branching, committing, and submitting a real pull request step by step.
Explore .gitignore Templates
GitHub's official collection of .gitignore templates for dozens of languages and tools — a good way to see real conventions for keeping a repo clean.
Build a CI/CD Pipeline
Fork one of GitHub's official starter workflows and adapt it into a real CI pipeline that lints, tests, and builds on every push.
Frequently Asked Questions
Common questions from people starting out with Git and GitHub
What's the difference between Git and GitHub?
Git is the version control tool itself — it runs on your computer and tracks changes to your files, with or without the internet. GitHub is a separate, web-based service that hosts Git repositories and adds collaboration features like pull requests, issues, and Actions on top of them. Other companies host Git repositories too, like GitLab and Bitbucket.
Do I need to know Git before learning GitHub?
Yes, at least the basics. GitHub's collaboration features (pull requests, forks, merges) are built directly on Git concepts like commits and branches, so a shaky grasp of local Git tends to make GitHub workflows confusing rather than easier.
Is Git hard to learn?
The everyday commands — status, add, commit, push, pull — are simple and you'll use them constantly within a day or two. What takes longer to feel natural is the mental model underneath: commits, branches, and how history is actually stored, which is why merge conflicts and rebases trip people up early on.
What's the difference between merging and rebasing?
Merging combines two branches by creating a new commit that ties their histories together, preserving exactly what happened and when. Rebasing replays your commits on top of another branch, producing a cleaner, linear history — but it rewrites commit history, so it's best avoided on branches other people are also working on.
How is GitHub different from GitLab or Bitbucket?
All three host Git repositories and offer pull/merge requests, issues, and CI/CD pipelines, so the core workflow transfers between them easily. GitHub has the largest open-source community and Actions ecosystem, GitLab is known for its all-in-one DevOps platform and strong built-in CI/CD, and Bitbucket integrates closely with other Atlassian tools like Jira.
How do I prepare for a Git-related technical interview?
Be able to explain branching and merging in your own words, know when to reach for rebase versus merge, understand what git reset and git revert each actually do to history, and be ready to walk through resolving a merge conflict — most interviewers care more about your mental model than memorised commands.
Track complete
From your first commit to a working CI/CD pipeline — that's the core of what nearly every engineering team expects around Git and GitHub. Keep it habitual: small commits, clear messages, and reviewed pull requests will serve you on every project after this one.
