Git & GitHub Mastery · Step 1 of 8
What Git Actually Is
Learn the Git core loop and undo mistakes safely — no more overwriting work or fearing the command line.
What you’ll walk away with
- Explain why version control exists and what problem it actually solves for anyone writing code
- Run the core Git loop — init, add, commit — to track changes in a real project
- Read a diff to see exactly what changed between commits before you commit it
- Set up a .gitignore file to keep unwanted files out of your repository
- Undo mistakes safely without losing work or corrupting your project history
- Build and inspect your own real Git history from scratch in the hands-on lesson
Questions people ask before they start
Do I need any prior coding experience to take this course?
No. The course starts with 'Why Version Control Exists,' which assumes no prior Git or programming background — it's built for someone starting from zero.
Will this teach me GitHub or GitHub Actions?
No. This course covers Git itself — init, add, commit, diffs, .gitignore, and undoing mistakes. GitHub and other platforms aren't part of this curriculum.
What does 'undoing mistakes safely' actually cover?
It's covered in the 'Diffs, .gitignore, and Undoing Mistakes' lesson, which walks through how to review changes and reverse them without losing or corrupting your work.
Is there a hands-on project, or is it all theory?
The final lesson, 'Hands-On: Your First Real Git History,' has you actually build and inspect a real Git history rather than just watching concepts explained.
How is this different from just reading a Git cheat sheet online?
The course walks through the core loop (init, add, commit) and the reasoning behind version control step by step, then has you apply it in a hands-on project rather than just listing commands.
Why is a cybersecurity company teaching a Git course?
Securafy, the company behind AI University, focuses on building software safely — and knowing how to track, review, and undo changes in your codebase is a foundational safety practice, which is why this course exists on the platform.
