-## RabbitMQ and Magento
-
-You need to make some changes in Magento in order to use RabbitMQ. For example in `/data/web/magento2/app/etc/env.php`:
-
-```php
-'queue' =>
-        array (
-            'amqp' =>
-                array (
-                    'host' => 'rabbitmqmaster',
-                    'port' => '5672',
-                    'user' => 'guest',
-                    'password' => 'guest',
-                    'virtualhost' => '/',
-                ),
-        ),
+## Creating RabbitMQ users
+
+You can also create your own RabbitMQ users. This can be done by in the RabbitMQ admin interface, as follows:
+
+1. Go to the RabbitMQ admin interface
+2. Click on the `Admin` tab
+3. Click on `Add a user`
+4. Fill in the username and password
+5. Click on `Add user`
+6. Click on the user you just created
+7. Click on `Set permission`
+
+## RabbitMQ and Magento 2
+
+To configure RabbitMQ in Magento 2, you can run the following command:
+
+```bash
+bin/magento setup:config:set \
+    --amqp-host="rabbitmqmaster" \
+    --amqp-port="5672" \
+    --amqp-user="guest" \
+    --amqp-password="guest" \
+    --amqp-virtualhost="/"
 ```
 
 Note: Hypernode provisions a non-default user called `hypernode-admin` but you are free to create new users.
