How These Guides Work
One Idea at a Time
Each guide shows one section per screen. The beginner explanation stays visible, while extra technical detail stays inside toggles you can open when you want it.
Built to Practise
You get worked examples, hands-on exercises, and quick checks throughout. Every command can be copied in one click.
Your Progress Stays Local
No account is needed, and nothing is sent anywhere. Your completed sections stay in this browser, and each guide tracks its own progress.
Works Offline
No setup, dependencies, or internet connection are needed. Open any guide directly from the file, including on a phone.
