skills/introduction-to-github ? reverse-engineered prompt

Build me a simple GitHub beginner exercise that teaches someone how to use GitHub in under an hour.

It should walk a new user through creating a branch, making a commit, opening a pull request, and merging it, with clear step by step instructions they can follow without needing any prior experience. The end result should be a short Markdown file they can use as a profile README, so the lesson feels practical and finished. Keep it friendly and easy to understand for students or first time GitHub users, and make sure it feels like a real hands on practice repo they can copy and start right away.
