Package description when publishing from action

I am trying to understand how to keep a latest Docker image’s description up to date. It does not appear that my README is copied over. If I edit the image’s description and generate a new version (done through an Action), then the old description is removed.

What am I missing?

Did you push docker image to GitHub Package Registry or Docker Hub ? If you push to Docker Hub, there is an action named Docker Hub Description to update a Docker Hub repository description from README.md. 

If you are pushing to Docker Package Registry, did you edit the image version description in github website?

It would be great if you could share your workflow yml file here.
