-In the above diagram you can see the initial integration supported. It involves the following components/actors:
+This sequence involves the following components/actors:
 
 - Consumers - The end users who need to use some computing services offered by the same Publisher as the data Publisher.
 - Operator-Service - Micro-service that is handling the compute requests.
