+#  Step 1 is to change your application name, save, exit, and cf push
+#  Step 2 - After you have your application running you can bind to the services below as described on predix.io

+  - name: Predix-HelloWorld-WebApp-<YourAppName> # Step 1: Change your application name

+    stack: cflinuxfs2
+
+    # Later, to Bind to services, uncomment the section below and enter the service name that you gave, e.g.
+    #services:
+    #        - my_redis_instance # change this to your redis service instance name
+    #        - my_viewsvc_instance # change this to your view service instance name

+    #  REDIS: redis-<num>
