+If you initialized your application with the [Nest CLI](https://docs.nestjs.com/cli/overview), [Express](https://expressjs.com/) framework will be installed by default along with Nest. Nest and NestJS Telegraf does not require Express for work. So if you don't plan to getting bot updates through webhooks, and you don't need a web server, you can remove Express. 
+
+To do this, change the `bootstrap` function in the `main.ts` file of your project on something like that:
+```typescript
+async function bootstrap() {
+  const app = await NestFactory.createApplicationContext(AppModule);
+}
+bootstrap();
+```
+
+This initializes Nest as a **standalone application** (without any network listeners).
+
+All that remains is to remove unused dependencies:
+```bash
+npm un @nestjs/platform-express @types/express
+```

+## Long polling
+
+By default, the bot receives updates using long-polling and requires no additional action.
+
+## Webhooks
+
 If you want to configure a telegram bot webhook, you need to get a middleware from `TelegrafProvider` for connect it in your `main.ts` file.
 
 To access it, you must use the `app.get()` method, followed by the provider reference:
