+To start the web service fully integrated with a Google Cloud Platform project a valid Google cloud credentials file is required to start the web service. Either complete the steps above to provision a new Google Cloud project or reach out to the maintainers of the project to be granted access to the production instance credentials.
+To start the web service without a Google cloud integration, use the `local` Spring Boot profile. To start the web service using the local profile add the following JVM parameters to the starting script, `-Dspring.profiles.active=local`.
 
 The location of credential key file is located in `web/service/src/main/resources/application.properties`.
