+## Translation of toolbar
+The package offers translations for the quill toolbar, it will follow the system locale unless you set your own locale with:
+```
+QuillToolbar(locale: Locale('fr'), ...)
+```
+Currently, translations are available for these locales:
+* `Locale('en')`
+* `Locale('de')`
+* `Locale('fr')`
+* `Locale('zh', 'CN')`
+
+### Contributing to translations
+The translation file is located at [lib/src/translations/toolbar.i18n.dart](lib/src/translations/toolbar.i18n.dart). Feel free to contribute your own translations, just copy the English translations map and replace the values with your translations. Then open a pull request so everyone can benefit from your translations!
