 ### Google Cloud Platform environments
 
-While running on Google Cloud Platform environments such as Google Compute
-Engine, Google App Engine and Google Kubernetes Engine, no extra work is needed.
-The **Project ID** and **Credentials** and are discovered automatically. Code
-should be written as if already authenticated. Just be sure when you [set up the
-GCE instance][gce-how-to], you add the correct scopes for the APIs you want to
-access. For example:
-
-  * **All APIs**
-    * `https://www.googleapis.com/auth/cloud-platform`
-    * `https://www.googleapis.com/auth/cloud-platform.read-only`
-  * **BigQuery**
-    * `https://www.googleapis.com/auth/bigquery`
-    * `https://www.googleapis.com/auth/bigquery.insertdata`
-  * **Compute Engine**
-    * `https://www.googleapis.com/auth/compute`
-  * **Datastore**
-    * `https://www.googleapis.com/auth/datastore`
-    * `https://www.googleapis.com/auth/userinfo.email`
