-## Library maintenance

We are fixing necessary bugs and adding essential features to ensure this library continues to meet your needs for accessing Google APIs.  Non-critical issues will be closed.  Any issue may be reopened if it is causing ongoing problems.

-## Description ##
 The Google API Client Library enables you to work with Google APIs such as Google+, Drive, or YouTube on your server.
 
+These client libraries are officially supported by Google.  However, the libraries are considered complete and are in maintenance mode. This means that we will address critical bugs and security issues but will not add any new features.
+
+## Google Cloud Platform
+
+For Google Cloud Platform APIs such as Datastore, Cloud Storage or Pub/Sub, we recommend using [GoogleCloudPlatform/google-cloud-php](https://github.com/GoogleCloudPlatform/google-cloud-php) which is under active development.
+
 ## Requirements ##
 * [PHP 5.4.0 or higher](http://www.php.net/)
 
-## Google Cloud Platform APIs
-If you're looking to call the **Google Cloud Platform** APIs, you will want to use the [Google Cloud PHP](https://github.com/googlecloudplatform/google-cloud-php) library instead of this one.
