 There is a set of custom Eslint rules to ensure code compatibility with the latest versions of third-party libraries.
 
-These custom rules are included using the `rulePaths` setting in the [Eslint Grunt configuration](https://github.com/magento/magento2/blob/2.4/dev/tools/grunt/configs/eslint.json).
+In previous versions of ESLint, these custom rules were included using the `rulePaths` setting in the [ESLint Grunt configuration](https://github.com/magento/magento2/blob/2.4/dev/tools/grunt/configs/eslint.json).
+
+However, since ESLint 9 has deprecated `rulePaths`, you must update the configuration accordingly.
+
+The following example shows the necessary changes to implement custom Eslint rules in the `dev/tools/grunt/configs/eslint.json` file.
+
+```json
+{
+  "file": {
+    "options": {
+      "overrideConfigFile": "vendor/magento/magento-coding-standard/eslint/eslint.config.mjs",
+      "useEslintrc": false
+    }
+  },
+  "test": {

+      "format": "junit",
+      "quiet": true
+    }
+  }
+}
+```
+
+### Applying custom rules
+
+To add or modify custom rules, update the `eslint.config.mjs` file in the `magento-coding-standard` repository.
+In the latest version of ESLint, the configuration has transitioned from using the legacy `.eslintrc` settings to the new flat configuration.
+Refer to the [migration guide](https://eslint.org/docs/latest/use/configure/migration-guide) in the ESlint documentation for detailed instructions on migrating to the new format.

Then it defines the connection name as `amqp` (or `stomp` for ActiveMQ Artemis) and the exchange as `magento` for each generated topic name.
 
 ## queue_consumer.xml
 
 The asynchronous/bulk API has one defined consumer which processes all asynchronous/bulk APIs messages.
 
 ```xml

 ### queue_topology.xml
 
 The message queue topology configuration links all auto-generated topic names with prefix `async.` to the `magento` exchange and defines the queue named `async.operations.all` as the destination for all messages.
 
 ```xml
-<exchange name="magento" connection="amqp">

 ### Create `queue_publisher.xml`
 
 The `queue_publisher.xml` file defines the exchange where a topic is published. Create this file with the following contents:
 
+**For RabbitMQ (AMQP):**
+
 ```xml
 <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework-message-queue:etc/publisher.xsd">

+    <publisher topic="<topic_name>" queue="<queue_name>" />
+</config>
+```
+
+**Note**: For ActiveMQ Artemis, the `<connection>` element is not required as the connection type is determined from `env.php`. When the topic name and queue name are different, you must specify the `queue` attribute in the `<publisher>` element.
+
 ### Create `queue_topology.xml`
 
 The `queue_topology.xml` file defines the message routing rules and declares queues and exchanges. Create this file with the following contents:
 
 ```xml
 <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework-message-queue:etc/topology.xsd">
