+## How to run the TCK tests
+
+The JSON-B TCK tests are produced as a Maven artifact where the tests use Arquillian + JUnit. To run the TCK tests using your implementation,
+include the TCK module and apply the appropriate Arquillian container. See the [Eclipse Yasson](https://github.com/eclipse-ee4j/yasson) repository for an example of this.
