When visiting the Docker Hub page of any image sourced from this repository, it isn't clear where the development happens (meaning, it is hard to find this repository from Docker Hub). For example: https://hub.docker.com/r/alpine/curl

Please add a paragraph to the Docker page to allow users to find out:

• where the source code is
• where they can find/report issues
• where they can contribute
• what has changed between versions

It could be as simple as:

This image is developed in the [alpine-docker/multi-arch-docker-images](https://github.com/alpine-docker/multi-arch-docker-images) repository on GitHub.
