 ## Пример интеграции с Elysia
 
+Этот пример демонстрирует, как интегрировать `@gramio/init-data` с Elysia с помощью удобного плагина с типо-безопасностью.
+
+`examples` в `x-init-data` заголовке являются валидными сгенерированными `init-data`, которые позволяют легче тестировать ваш API в OpenAPI клиентах.

 ## Elysia integration example
 
+This example shows how to integrate `@gramio/init-data` with Elysia via convenient plugin with type safety.
