 - **Run:** `bunx expo start` or `bun run start` — then press `a` for Android or `i` for iOS, or scan the QR code with Expo Go.

 ## 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.
 
 The app targets both native and web (responsive) and uses the same backend (d-sports-api) as the PWA for API and checkout flows.
 
+## CI/CD
+
+**Xcode Cloud** handles iOS builds. The `ios/ci_scripts/ci_post_clone.sh` script runs after cloning to set up the build environment:
+
+- Installs a local Node.js (v20.18.0) if not already present—required for CocoaPods autolinking
+- Runs `pod install` via Bundler (if available) or directly
