 import 'package:pnta_flutter/pnta_flutter.dart';
 
 void main() async {

-    autoHandleLinks: true,  // Auto-open links from background notifications
-    showSystemUI: false,    // Hide system notification UI when app is in foreground

 ### Core Methods
 
-#### `PntaFlutter.initialize(String projectId, {bool autoHandleLinks, bool showSystemUI})`
+#### `PntaFlutter.initialize(String projectId, {Map<String, dynamic>? metadata, bool requestPermission, bool autoHandleLinks, bool showSystemUI})`
 
-Initializes the plugin with your project ID and configuration options.
+Main initialization method that handles everything for most apps:
 
 -   `projectId`: Your PNTA project ID (format: `prj_XXXXXXXXX`) from [app.pnta.io](https://app.pnta.io)
--   `autoHandleLinks`: Automatically handle `link_to` URLs when notifications are tapped from background/terminated state
--   `showSystemUI`: Show system notification banner/sound when app is in foreground
+-   `metadata`: Optional device metadata to include during registration
+-   `requestPermission`: Whether to request permission and register device immediately (default: `true`)
+-   `autoHandleLinks`: Automatically handle `link_to` URLs when notifications are tapped (default: `true`)
+-   `showSystemUI`: Show system notification banner/sound when app is in foreground (default: `false`)
 
-#### `PntaFlutter.requestNotificationPermission()`
+Returns `Future<String?>` - the device token if permission was granted and device registered, null otherwise.
 
-Requests notification permission from the user. Returns `Future<bool>`.
+#### `PntaFlutter.requestPermission({Map<String, dynamic>? metadata})`
 
-#### `PntaFlutter.identify({Map<String, dynamic>? metadata})`
+For delayed permission scenarios. Must be called after `initialize()` with `requestPermission: false`.
 
-Registers the device with your PNTA project using the project ID from initialization. Can be called in two ways:
+-   `metadata`: Optional device metadata to include during registration (merged with metadata from initialize)
 
--   **Without storing token**: `await PntaFlutter.identify(metadata: {...})`
--   **With token returned**: `final token = await PntaFlutter.identify(metadata: {...})`
+Returns `Future<String?>` - the device token if permission was granted and device registered, null otherwise. **Note: You can ignore the return value if you don't need the token.**
 
-Returns the device token as `Future<String?>` if you need it for your own backend or logging.
+#### `PntaFlutter.updateMetadata(Map<String, dynamic> metadata)`
 
-#### `PntaFlutter.updateMetadata({Map<String, dynamic>? metadata})`
-
-Updates device metadata without re-registering. Uses the project ID from initialization. Returns `Future<void>`.
+Updates device metadata without re-registering. Must be called after successful initialization. Returns `Future<void>`.
