-In this quickstart, you'll create a publisher microservice and a subscriber microservice to demonstrate how Dapr enables a publish-subcribe pattern. The publisher will generate messages of a specific topic, while subscribers will listen for messages of specific topics.

+In this quickstart, there is a publisher microservice `checkout` and a subscriber microservice `order-processor` to demonstrate how Dapr enables a publish-subscribe pattern. `checkout` generates messages and publishes to a specific orders topic, and `order-processor` subscribers listen for messages of topic orders.
