Frequently Asked Questions

Is this site really free?

Yes. Every tutorial is free to read. We may show ads to cover hosting.

Do I need an account?

No. Your progress is stored in your browser and never leaves your device.

How do I sync progress across devices?

You can’t — there’s no backend. If you need cross-device sync, you’ll have to remember where you were.

How are tutorials organized?

The hierarchy is Track → Course → Chapter. Tracks are big-picture curricula; courses are focused topics; chapters are individual lessons.
