+## Flutter setup
+
+ To use AppiumFlutterLibrary you will need to make a simple setup in your Flutter project.
+ 
+ At first, include flutter_driver package to your dev dependencies at *pubspec.yaml*:
+ 
+ ```yaml
+ 
+dev_dependencies:
+  flutter_test:
+    sdk: flutter
+  flutter_driver:
+    sdk: flutter
+
+ ```
+ 
+ Then go to your *main.dart* file and add **enableFlutterDriverExtension()** to your main function before **runApp()**
+ 
+ ```dart
+import 'package:flutter/material.dart';
+import 'package:flutter_driver/driver_extension.dart';
+
+void main() {
+  enableFlutterDriverExtension();
+  runApp(const MyApp());
+}
+
+... 
+ ```
