How do I inform QNAP (and other users of DocukerHub) if my Docker Image is Intel or Arm

QNAP ContainerStation supports searching for Docker images on Docker Hub . QNAP ContainerStation is supported on both their Intel and Arm platforms. I have an Intel and an Arm Image of my application, if user searches for image (songkong) both are displayed but of course only the Intel version will work on Intel QNAP and only Arm version will work on Arm QNAP.

It would be better for the customer if QNAP would just list the valid one, since QNAP dont make it very clear what the cpu is for their various models. Is there anything I can add to my Dockerfile, or anything I can within DockerHub repository to help QNAP do this ?
