+Authentication
+--------------
+
+There are multiple ways to authenticate to use Google Cloud services.
+
+1. When using `gcloud-java` libraries from within Compute/App Engine, no additional authentication steps are necessary.
+2. When using `gcloud-java` libraries elsewhere, there are two options:
+  * [Generate a JSON service account key](https://cloud.google.com/storage/docs/authentication?hl=en#service_accounts).  Supply a path to the downloaded JSON credentials file when building the options supplied to datastore/storage constructor.
+  * If running locally for development/testing, you can use use [Google Cloud SDK](https://cloud.google.com/sdk/?hl=en).  To use the SDK authentication, [download the SDK](https://cloud.google.com/sdk/?hl=en) if you haven't already.  Then login using the SDK (`gcloud auth login` in command line), and set your current project using `gcloud config set project PROJECT_ID`.
 
 Google Cloud Datastore
 ----------------------
 
-[Google Cloud Datastore][cloud-datastore] is a fully managed, schemaless database for
-storing non-relational data. Cloud Datastore automatically scales with
-your users and supports ACID transactions, high availability of reads and
-writes, strong consistency for reads and ancestor queries, and eventual
-consistency for all other queries.
