+### Tutorials
+
+The app has an interactive tutorial system (`static/js/features/tutorials.js`) with a generic engine, spotlight overlay, tooltip positioning, and keyboard navigation. Tutorials exist for:
+- **Getting started** (header-level walkthrough of all tabs and controls)
+- **Per-tab tutorials** (Dashboard, Targets, Sources, Profiles) triggered by `?` buttons
+- **Device card tutorial** and **Calibration tutorial** (context-specific)
+
+When adding **new tabs, sections, or major UI elements**, update the corresponding tutorial step array in `tutorials.js` and add `tour.*` i18n keys to all 3 locale files (`en.json`, `ru.json`, `zh.json`).
+
 ## General Guidelines
 
 - Always test changes before marking as complete
