# Samples and tutorials

While [Sample apps](/docs/resources/examples) offers **ready-to-run code**, here the focus is the **narrated
walkthrough** — building something from scratch, explaining each step.

## Official tracks (start here)
| Track | For |
|---|---|
| [Get Started](/docs/get-started) | from zero to your 1st app on the desktop, in ~10 min |
| [Learn — Fundamentals](/docs/learn) | a 12-step guided course building a complete app |
| [Migrate from another framework](/docs/migrate) | Flutter/Compose/SwiftUI/React Native/TotalCross |
