+4. Other AMQP transports
+
+The package uses [enqueue/amqp-lib](https://github.com/php-enqueue/enqueue-dev/blob/master/docs/transport/amqp_lib.md) transport which is based on [php-amqplib](https://github.com/php-amqplib/php-amqplib). 
+There is possibility to use any [amqp interop](https://github.com/queue-interop/queue-interop#amqp-interop) compatible transport, for example `enqueue/amqp-ext` or `enqueue/amqp-bunny`.
+Here's an example on how one can change the transport to `enqueue/amqp-bunny`.
+
+First, install the package:
+
+```bash
+$ composer require enqueue/amqp-bunny:^0.8
+```
+  
+and change the factory class:
+
+```php
+<?php
+// config/queue.php
+
+return [
+    'connections' => [
+        'rabbitmq' => [
+            'driver' => 'rabbitmq',
+            'factory_class' => \Enqueue\AmqpBunny\AmqpConnectionFactory::class,
+        ],
+    ],
+];
+```
+
 #### Usage
 
 Once you completed the configuration you can use Laravel Queue API. If you used other queue drivers you do not need to change anything else. If you do not know how to use Queue API, please refer to the official Laravel documentation: http://laravel.com/docs/queues
