+At times you may need to access the native `Telegraf` instance. You can inject the Telegraf by using the `@InjectBot()` decorator as follows:
+
+```typescript {8} title="src/echo/echo.service.ts"
+import { Injectable } from '@nestjs/common';
+import { InjectBot } from 'nestjs-telegraf';
+import { Telegraf } from 'telegraf';
+import { TelegrafContext } from '../common/interfaces/telegraf-context.interface.ts';
+
+@Injectable()
+export class EchoService {
+  constructor(@InjectBot() private bot: Telegraf<TelegrafContext>) {}
+  ...
+}
+```
+
+If you run [multiple bots](/extras/multiple-bots) in the same application, explicitly specify the bot name:
+
+```typescript {8} title="src/echo/echo.service.ts"
+import { Injectable } from '@nestjs/common';
+import { InjectBot } from 'nestjs-telegraf';
+import { Telegraf } from 'telegraf';
+import { TelegrafContext } from '../common/interfaces/telegraf-context.interface.ts';
+
+@Injectable()
+export class EchoService {
+  constructor(@InjectBot('cats') private bot: Telegraf<TelegrafContext>) {}
+  ...
+}
+```
