+### Octane support
+
+This package supports laravel octane by
+default. [To keep the AMQP connection alive](https://www.cloudamqp.com/blog/part4-rabbitmq-13-common-errors.html),
+you have to configure octane to `warm` the connection, by adding **'amqp'** to the warm array in octane configurations.
+
+```php
+// config/octane.php
+// ... 
+'warm' => [
+    // ... 
+    'amqp', // <-- this line
+],
+```
