+Integration for the [`logging`](https://pub.dev/packages/logging) package.
+
+#### Usage
+
+- Sign up for a Sentry.io account and get a DSN at http://sentry.io.
+
+- Follow the installing instructions on [pub.dev](https://pub.dev/packages/sentry/install).
+
+- Initialize the Sentry SDK using the DSN issued by Sentry.io and add the `LoggingIntegration`
+
+```dart
+import 'package:sentry/sentry.dart';
+
+Future<void> main() async {
+  await Sentry.init(
+    (options) {
+      options.dsn = 'https://[email protected]/example';
+      options.addIntegration(LoggingIntegration());
+    },
+    appRunner: initApp, // Init your App.
+  );
+}
+
+void initApp() {
+  // your app code
+}
+```
