+To run:
+    * `mvn clean install`
+    * `./list_resources_example.sh <YOUR-PROJECT-ID>
+    * `./run_custom_metrics.sh <YOUR-PROJECT-ID>

-To run locally:
-    * `mvn clean install`
-    * `./list_resources_example.sh <YOUR-PROJECT-ID>
-    * `./run_custom_metrics.sh <YOUR-PROJECT-ID>
+On Google Compute Engine, the credentials should be found automatically, but require that
+you create the instance with the correct scopes. 
+
+    gcloud compute instances create --scopes="https://www.googleapis.com/auth/cloud-platform,https://www.googleapis.com/auth/compute,https://www.googleapis.com/auth/compute.readonly" test-instance
+
+If you did not create the instance with the right scopes, you can still upload a JSON service 
+account and set GOOGLE_APPLICATION_CREDENTIALS as described below.
+
+## Using a Service Account
+
+In non-Google Cloud environments, GCE instances created without the correct scopes, or local
+workstations if the `gcloud beta auth application-default login` command fails, use a Service 
+Account by doing the following:
+
+* Go to API Manager -> Credentials
+* Click 'New Credentials', and create a Service Account or [click  here](https://console.cloud.google
+.com/project/_/apiui/credential/serviceaccount)
+ Download the JSON for this service account, and set the `GOOGLE_APPLICATION_CREDENTIALS`
+ environment variable to point to the file containing the JSON credentials.
+
+
+    export GOOGLE_APPLICATION_CREDENTIALS=~/Downloads/<project-id>-0123456789abcdef.json
