+## Validate example

 After installing the examples you can check for the services.
 
+```
 service:list EntityManagerFactory

 You should see a service for the persistence unit "tasklist".
 
+```
 service:list TaskService

 You should see a service provided by either the tasklist.blueprint or tasklist.ds bundle depending on the example you installed.
