+Read the [companion blog article](https://reflectoring.io/consumer-driven-contract-consumer-spring-cloud-contract/) to this repository.
 
 ## Getting Started
 
+* have a look at the [contract](/src/test/resources/contracts)
 * have a look at the [feign client](/src/main/java/io/reflectoring/UserClient.java)
-* have a look at the [consumer test](/src/test/java/io/reflectoring/UserServiceConsumerTest.java)
+* have a look at the [consumer test](/src/test/java/io/reflectoring/UserClientTest.java)
-* run `./gradlew build` to run all tests and create pact files into the folder `target/pacts`
+* run `./gradlew publishToMavenLocal` in the [producer project](../spring-cloud-contract-provider) 
-* run `./gradlew pactPublish` to publish the pact files to a Pact Broker (must specify Pact Broker location and credentials in `build.gradle`)
+  to create a provider stubs
+* run `./gradlew build` in this project to verify the feign client against the stub
