 ### 2.2 Create an IAuthenticationProvider object
 
-An instance of the **GraphServiceClient** class handles building requests, sending them to the Microsoft Graph API, and processing the responses. To create a new instance of this class, you need to provide an instance of `IAuthenticationProvider`, which can authenticate requests to Microsoft Graph.
-
-For an example of authentication in a client application, see the [MSGraph SDK Android MSA Auth for Android Adapter](https://github.com/microsoftgraph/msgraph-sdk-android-msa-auth-for-android-adapter).

 ## 3. Make requests against the service
 
-After you have a HttpClient that is authenticated, you can begin making calls against the service. The requests against the service look like our [REST API](https://developer.microsoft.com/en-us/graph/docs/concepts/overview).
