+## Global Configuration
+
+The app demonstrates how to configure the `LocalData` library globally during startup in `SecureStorageSampleApp.swift`:
+
+- **Encryption**: Customized Keychain service (`SecureStorageSample`) and account (`AppMasterKey`) names to isolate the library's master encryption key from other apps.
+- **Sync**: Set a custom `maxAutoSyncSize` of 50KB to control which data is automatically synchronized to the Apple Watch, overriding the library's 100KB default.
+
+This approach centralizes infrastructure settings and avoids hardcoding environment-specific values within individual storage keys.
