Git 101 — Practice Repo

The companion repository for the Git 101 course by Fynes Forge.

How This Repo Works

Unlike a course where you write answers into files, Git is learned by doing. This repo gives you a real environment to practise in — branches to switch between, a commit history to inspect, conflicts to resolve, and files to stage, stash, and reset.

This repo is your playground. Break things. That's the point.

Getting Started

1. Fork this repo

Click Fork in the top-right corner of GitHub. This creates your own personal copy.

2. Clone your fork

git clone git@github.com:<your-username>/git-101.git
cd git-101

No SSH key yet? Grade 3 covers exactly this. For now you can clone with HTTPS:

git clone https://github.com/<your-username>/git-101.git

3. Work through the grades in order

Each grade has its own folder with a README.md containing your exercises.

Tips

• Run git status constantly — it tells you exactly where you are.
• Run git log --oneline --graph --all to visualise the full branch history.
• Made a mess? Every grade's README.md has a Reset section to get back to a clean state.
• Check tips/cheatsheet.md for a quick command reference.
