# Edit a Amazon MQ for RabbitMQ Configuration Revision
<a name="edit-current-rabbitmq-configuration-console"></a>

 The following instructions describe how to edit a configuration revision for your broker. 

1. Sign in to the [Amazon MQ console](https://console.aws.amazon.com/amazon-mq/).

1. From the broker list, select your broker (for example, **MyBroker**) and then choose **Edit**.

1. On the ***MyBroker*** page, choose **Edit**.

1. On the **Edit *MyBroker*** page, in the **Configuration** section, select a **Configuration** and a **Revision** and then choose **Edit**.
**Note**  
Unless you select a configuration when you create a broker, the first configuration revision is always created for you when Amazon MQ creates the broker.

   On the ***MyBroker*** page, the broker engine type and version that the configuration uses (for example, **RabbitMQ 3.xx.xx**) are displayed.

1. On the **Configuration details** tab, the configuration revision number, description, and broker configuration in Cuttlefish format are displayed.
**Note**  
Editing the current configuration creates a new configuration revision.

1. Choose **Edit configuration** and make changes to the Cuttlefish configuration.

1. Choose **Save**.

   The **Save revision** dialog box is displayed.

1. (Optional) Type `A description of the changes in this revision`.

1. Choose **Save**.

   The new revision of the configuration is saved.
**Important**  
Making changes to a configuration does *not* apply the changes to the broker immediately. To apply your changes, you must wait for the next maintenance window or [reboot the broker](amazon-mq-rebooting-broker.md).  
Currently, you can't delete a configuration.
