I read the guide and came here looking to see if there was a docker image. I just don't want to blindly pipe-sh on my host machine (would need to review what rustup is doing first). On top of that, 'wait 2 hours' is not something I want to do when I want to kick the tires on a Hello World. This is a great example of docker-for-dev. Don't bother setting up the specific versions of compilers and then worry about clean-up afterward. The guide should be 2 lines: docker pull, then docker run.
