 For existing customers planning to migrate to the new Amplify Android v2, we recommend reviewing our [migration guide](https://github.com/aws-amplify/amplify-android/blob/main/documents/MobileSDK_To_AmplifyAndroid.md).
 
-For new projects, we recommend using the latest v2 version of [AWS Amplify Library for Android](https://docs.amplify.aws/start/q/integration/android/) to quickly implement common app use cases like Authentication, Storage, Push Notifications and more.

 Note: v2 of Amplify Library for Android (currently GA) is built on top of [the AWS SDK for Kotlin](https://aws.amazon.com/sdk-for-kotlin/). You can access this underlying SDK via [the Escape Hatch from AWS Amplify](https://docs.amplify.aws/lib/project-setup/upgrade-guide/q/platform/android/#escape-hatches).
 
-You can also use AWS Amplify with [your existing AWS cloud resources](https://docs.amplify.aws/lib/project-setup/use-existing-resources/q/platform/android/). If you are unable to find features you are looking for in Amplify, please open an issue in [the Amplify Library for Android GitHub repo](https://github.com/aws-amplify/amplify-android/issues/new/choose) and we will be happy to consider you request.
