 ## Getting started
 
-1. Clone the repository and run `bun install`.
-2. Configure environment (Clerk, RevenueCat, Thirdweb, API base URL) per repo README.
-3. Run `bunx expo start`.
-4. For development builds: `bun run build:dev` (EAS) or run with Expo dev client.
+```bash
+# Install dependencies
+bun install
 
-The app targets both native and web (responsive) and uses the same backend (d-sports-api) as the PWA for API and checkout flows.
+# Start development server
+bunx expo start
+# Press 'a' for Android, 'i' for iOS, or scan QR with Expo Go
+
+# TypeScript check
+bun tsc --noEmit
+```
+
+Configure environment variables (Clerk, RevenueCat, Thirdweb, API base URL) per the repo README. For development builds use `bun run build:dev` (EAS) or run with Expo dev client.

+
+## Architecture patterns
+
+- **File-based routing** via Expo Router with route groups `(tabs)`, `(auth)`, `(onboarding)`
+- **Modular screen architecture** — screen files contain only JSX; state/effects/handlers live in dedicated hooks
+- **Extracted sub-components** — wallet and shop screens decomposed into `components/wallet/` and `components/shop/` with barrel exports
+- **Zustand + MMKV** for global state with synchronous persistence
+- **React Context** for auth, collectibles, navbar visibility
+- **API client layer** in `lib/api/` with MMKV cache fallback
+- **Crypto checkout** via Thirdweb SDK calling PWA backend for on-chain payments
+- **PWA-ready** — responsive desktop layout, web hover states, keyboard nav
