+#### Creating a Containerized Image using `aem_cntrl`
+
+In order to create a containerized image...
+* Create the FluentForms jar files (`fluentforms.core-0.0.x-SNAPSHOT.jar`, and `rest-services.server-0.0.x-SNAPSHOT.jar`) from their projects within this GitHub repo.
+* Download the latest AEM installation files (quickstart jar plus any service pack zips).
+* Obtain a copy of your `licence.properties` file from you current AEM installation.
+* Create an `aem_cntrl-0.0.x-SNAPSHOT.jar` file from the [`aem_cntrl` project](https://github.com/4PointSolutions/aem-utils/tree/main/aem_cntrl).
+* Follow the instructions in the [`aem_container` project](https://github.com/4PointSolutions/aem-utils/blob/main/aem_container/README.md) to create a container image.
+
+Once the container is built, configure the project as [outlined above](#containerized-aem-image-via-testcontainers) and run the tests.
+
