 In `app/app.yaml` there's an application name that in the above steps was set to fake-application-name.  After registering an application on Google App Engine, use any text editor to change the line that starts with `application: fake-application-name` to instead read `application: <your-instance-name>`. You can also run the script again:
 
 {{{
-scripts/gen_app_yaml.py -f proper-application-name
+scripts/gen_app_yaml.py -o devvin -f proper-application-name 
 }}}
