I wasn't a fan of having to compile the dev branch of both emscripten itself, and clang, each time I wanted to try the latest (hence the 'wait 2 hours' in the blog)

I thus asked about providing a Docker image - the person that handles the builds and the SDKs says that nightly builds are on the way: https://github.com/kripken/emscripten/issues/4682#issuecomme...

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.
