+#### Replace translations in one go
+
+You can replace all the translations for a single key using this method:
+
+```php
+public function replaceTranslations(string $key, array $translations)
+```
+
+Here's an example:
+
+```php
+$translations = ['en' => 'hello', 'es' => 'hola'];
+
+$newsItem->setTranslations('hello', $translations);
+$newsItem->getTranslations(); // ['en' => 'hello', 'es' => 'hola']
+
+$newTranslations = ['en' => 'hello'];
+
+$newsItem->replaceTranslations('hello', $newTranslations);
+$newsItem->getTranslations(); // ['en' => 'hello']
+```
+
 #### Setting the model locale
 The default locale used to translate models is the application locale,
 however it can sometimes be handy to use a custom locale.
