 Get started with the Microsoft Graph SDK for Java by integrating the [Microsoft Graph API](https://graph.microsoft.io/en-us/getting-started) into your Java application!
 
+> **Note:** this SDK allows you to build applications using the [v1.0](https://docs.microsoft.com/en-us/graph/use-the-api#version) of Microsoft Graph. If you want to try the latest Microsoft Graph APIs under beta, use our [beta SDK](https://github.com/microsoftgraph/msgraph-beta-sdk-java) instead.

 ### 1.3 Enable ProGuard (Android)
+
 The nature of the Graph API is such that the SDK needs quite a large set of classes to describe its functionality. You need to ensure that [ProGuard](https://developer.android.com/studio/build/shrink-code.html) is enabled on your project. Otherwise, you will incur long build times for functionality that is not necessarily relevant to your particular application. If you are still hitting the 64K method limit, you can also enable [multidexing](https://developer.android.com/studio/build/multidex.html).

 For an example of authentication in a Java desktop client application, see the [Preview msgraph-sdk-java-auth](https://github.com/microsoftgraph/msgraph-sdk-android-msa-auth-for-android-adapter) and for an Android application see [Preview msgraph-sdk-android-auth](https://github.com/microsoftgraph/msgraph-sdk-android-auth).
 
 ### 2.3 Get a GraphServiceClient object
+
 After you have set the correct application ID and URL, you must get a **GraphServiceClient** object to make requests against the service. The SDK stores the account information for you, but when a user signs in for the first time, it invokes the UI to get the user's account information.
