 Run `npm install` to load the needed javascript libraries and then `npm run test` to
 run the tests. After the tests have successfully run the created pact file will be
 created in the folder `pacts`. 
+
+Then, you can call `npm run publish-pacts` to publish the pact files to a [Pact Broker](https://github.com/pact-foundation/pact_broker).
+You must set the following npm configs for the `publish-pacts` script to work:

+# Consumer-Driven-Contract Test for a Spring Boot Provider
+ 
+This repo contains an example of consumer-driven-contract testing for a Spring
+Boot API provider. The corresponding consumer to the contract is
+implemented in the module `pact-angular`.
+
+The contract is created and verified with [Pact](https://docs.pact.io/).
+
+Before running the build, you need to follow the instructions on the [consumer-side](../pact-angular/)
+to create the consumer-driven contract file (pact file).
+
+## Running the application
+
+The interesting part in this code base is the class `UserControllerProviderTest`.
+You can run the tests with `gradlew test` on Windows or `./gradlew test` on Unix.
