+## How to setup localization
+In order to support other languages, developers need to configure localization settings like the settings for the time picker. Example for english and korean:
+
+```dart
+class MyApp extends StatelessWidget {
+  const MyApp({Key? key}) : super(key: key);
+
+  @override
+  Widget build(BuildContext context) {
+    return MaterialApp(
+      title: 'Duration Picker Demo',
+      theme: ThemeData(
+        primarySwatch: Colors.blue,
+      ),
+      localizationsDelegates: [
+        DurationPickerLocalizations.delegate,
+        GlobalMaterialLocalizations.delegate,
+        GlobalWidgetsLocalizations.delegate,
+        GlobalCupertinoLocalizations.delegate,
+      ],
+      supportedLocales: [Locale('en'), Locale('ko')],
+      home: const MyHomePage(title: 'Duration Picker Demo'),
+    );
+  }
+}
+```
+
+## How to add more languages
+
+1. Add a localizations class in `localizataions` dir.
+
+```dart
+class DurationPickerLocalizationsKo extends DurationPickerLocalizations {
+  @override
+  String get baseUnitHour => '시간';
+
+  @override
+  String get baseUnitMillisecond => '밀리초';
+
+  ...
+}
+```
+
+The class should extend `DurationPickerLocalizations`. This makes it easy to write everything you should write.
+
+2. Add the language code to the `supportedLocales` array in `_DurationPickerLocalizationDelegate`.
+
+```dart
+class _DurationPickerLocalizationDelegate
+    extends LocalizationsDelegate<DurationPickerLocalizations> {
+  const _DurationPickerLocalizationDelegate();
+
+  static const supportedLocales = ['en', 'ko'];
+
+  ...
+
+}
+```
+
+3. Return a `DurationPickerLocalizations` implementation as locale at `load` method in `_DurationPickerLocalizationDelegate`.
+
+```dart
+@override
+  Future<DurationPickerLocalizations> load(Locale locale) async {
+    switch (locale.languageCode) {
+      case 'ko':
+        return DurationPickerLocalizationsKo();
+      default:
+        return DurationPickerLocalizationsEn();
+    }
+  }
+```
+
