 ### Importing the dependency
 
+At the moment the module is published to GitHub Packages only,
+see [Issue #56](https://github.com/wiremock/wiremock-testcontainers-java/issues/56)
+for publishing to Maven Central.
+For the moment, you can use the authenticated GitHub Packages server or
+[JitPack](https://jitpack.io/) to add the dependency in your projects.
