+At times you may need to access the native `Telegraf` instance. For example, you may want to connect stage middleware. You can inject the Telegraf by using the `@InjectBot()` decorator as follows:
+```typescript
+import { Injectable } from '@nestjs/common';
+import { InjectBot, TelegrafProvider } from 'nestjs-telegraf';
+
+@Injectable()
+export class BotSettingsService {
+  constructor(@InjectBot() private bot: TelegrafProvider) {}
+}
+```
