Free online courseGit and GitHub tutorials

Course Description

Strong version control skills are a must for modern developers, QA engineers, data teams, and anyone who ships code. This free online course helps you build practical confidence with Git and GitHub so you can work faster, avoid mistakes, and collaborate smoothly on real projects. Whether you are just starting out or you have used Git before but still feel unsure about day-to-day workflows, you will gain a clear mental model of how Git tracks changes and how GitHub fits into team collaboration.

You will begin with the fundamentals: what Git is, why it is used across the industry, and how to set it up correctly on your machine. From there, you will create your first repository and understand the three-stage architecture that makes Git so powerful. As you practice, you will learn how to move changes through the workflow with the right commands and develop habits that keep your history clean and your work easy to review.

Collaboration is where Git becomes essential, and this course focuses on the skills that matter most in team environments. You will learn how pushing and pulling connect local work with a remote repository, how cloning helps you start contributing quickly, and how git diff helps you inspect changes before you commit. You will also clear up common confusion points, such as when to use git add -A versus git add ., so your staging area reflects exactly what you intend to share.

To keep projects tidy and professional, you will practice ignoring files with a .gitignore so you do not accidentally commit build outputs, local settings, or sensitive artifacts. You will also get comfortable with branching, a core workflow for building features safely and reviewing code, and you will learn how to delete local and remote branches once work is complete. By the end, you will be able to navigate everyday Git and GitHub tasks with less guesswork and more control, making your development workflow more reliable and career-ready.
