+Google Cloud Storage
+----------------------
+
+[Google Cloud Storage][cloud-storage] is a durable and highly available
+object storage service. Google Cloud Storage is almost infinitely scalable
+and guarantees consistency: when a write succeeds, the latest copy of the
+object will be returned to any GET, globally.
+
+See the [Google Cloud Storage docs][cloud-storage-activation] for more details on how to activate
+Cloud Storage for your project.
+
+See the ``gcloud-java`` API [storage documentation][storage-api] to learn how to interact
+with the Cloud Storage using this Client Library.
