It used to be that docker could be installed literally by downloading the docker binary, then it was a single curl command. Now the documentation looks like this: https://www.docker.com/get-docker

You press "get docker community image". Then you find your distro. Go to "download from the docker store", discover that there is no dowload link https://store.docker.com/editions/community/docker-ce-server... then you click on the long form link to the docs. Which gets you here: https://docs.docker.com/engine/installation/linux/docker-ce/...

And then that is not simple at all.

So much for fat binaries making things easy. Good-ness grief.
