+Now you can use categories without configuring each one that is similar to Yii 1.1 behavior.
+Messages for the category will be loaded from a file under default translation `basePath` that is `@app/messages`:
 
 ```php
-# not_specified_category.php file under @app/messages directory.
-
-return [
-	'message from not specified category' => 'сообщение из неуказанной категории',
-];
+echo Yii::t('not_specified_category', 'message from unspecified category');
 ```
 
-* Use your category as before.
-
-```php
-echo Yii::t('not_specified_category','message from not specified category');
-```
+Message will be loaded from `@app/messages/<LanguageCode>/not_specified_category.php`.
