+## Использование со сторонними рендерами твига
+
+Если на проекте подключен иной обработчик твиг-шаблонов, то необходимо выключить регистрацию обработчика модуля.
+Необходимо перейти в настройки модуля и отключить свойство "Подключать обработчик шаблонов twig".
+
+В нужном объекте twig зарегистрировать расширение, получив его через метод `\Mail\Mjml\Mjml\Service\ExtensionService::compileTwigExtension`
+
+В перечень обрабатываемых файлов twig добавить расширение mjml.twig
+
+```php
+$arCustomTemplateEngines['twig'] = [
+    'templateExt' => ['mjml.twig', 'twig'],
+];
+```
+
 ## Использование
 
 В шаблоне письма выбрать режим "Визуальный редактор" и подключить компонент.
