Image description: tag list

Hi all, I’m quite new to Docker, so feel free to beat me to death if the question was already asked and answered multiple times: I tried a forum search, but I got no existing threads on this.

My question is: is there any established / consolidated way to generate the nice list visible as Supported tags and respective Dockerfile links you can see on any of the official image description?

if you have a github/bitbucket automated build, this could be achieved by providing a README.md.
Cannot be automated, it’s handwritten.

Example Docker Hub Project:
https://hub.docker.com/r/think/notebook/
with README.md here:
