 ### ✨ Features
 - **Router Observers**: `MagicRouter.instance.addObserver()` enables NavigatorObserver integration for analytics/monitoring (Sentry, Firebase Analytics, custom observers). Observers are passed to GoRouter automatically. (#31)
 - **Network Driver Plugin Hook**: `DioNetworkDriver.configureDriver()` exposes the underlying Dio instance for SDK integrations (sentry_dio, certificate pinning, custom adapters). (#32)
+- **Custom Log Drivers**: `LogManager.extend()` enables custom LoggerDriver registration (Sentry, file, Slack). Config-driven resolution with built-in override support. (#33)

 ```
 
-> [!NOTE]
-> The `registerDriver` method is a convention. If `LogManager` doesn't support it natively, you can extend it or customize resolution logic.
+This follows the same `extend()` pattern as `Auth.manager.extend(...)` for custom auth guards. The factory receives the channel's config map and returns a `LoggerDriver` instance.
 
 Then use it in your config:

+### Custom Drivers
+
+Register custom log drivers via `LogManager.extend()` — follows the same pattern as `Auth.manager.extend(...)`:
+
+```dart
+// In a ServiceProvider boot():

+Custom drivers implement the `LoggerDriver` abstract class. They can be referenced in config by name and included in stack channels.
