+## Custom language directory
+
+By default, the plugin will look for language files in the `resources/lang` directory if the laravel version is minor than v9, otherwise it will look for language files in the `lang` directory. You can specify a custom directory by passing the `absoluteLanguageDirectory` option to the plugin.
+
+```js

+plugins: [
+    laravelTranslations({
