+### Migrate to version 18+
+
+Version 18 does not expose the module because it has been removed. Therefore, you need to remove all imports of the `JsonApiModule`.
+
+Additionally, ensure that `HttpClientModule` is provided in your application, as it was previously imported and re-exported by `JsonApiModule`.
