+### Manage resources of a service bus namespace
+
+`ServiceBusManagementClient` lets you manage a namespace with CRUD operations on the entities(queues, topics, and subscriptions) and on the rules of a subscription.
+
+- Supports authentication with a service bus connection string as well as with the AAD credentials from `@azure/identity` similar to the `ServiceBusClient`.
+
+```js
+// Get the connection string from the portal
+// OR
+// use the token credential overload, provide the host name of your Service Bus instance and the AAD credentials from the @azure/identity library
+const serviceBusManagementClient = new ServiceBusManagementClient("<connectionString>");
+
+// Similarly, you can create topics and subscriptions as well.
+const createQueueResponse = await serviceBusManagementClient.createQueue(queueName);
