 An instance of the **GraphServiceClient** class handles building client. To create a new instance of this class, you need to provide an instance of **AuthenticationProvider**, which can authenticate requests to Microsoft Graph.
 
-Note: This SDK offers an asynchronous API by default. Async is a concurrency model that is far more efficient than multi-threading, and can provide significant performance benefits and enable the use of long-lived network connections such as WebSockets. We support the popular async envronments such as `asyncio`, `anyio` or `trio`. For authentication you need to use one of the async credential classes from `azure.identity`.
