I don't use or support Docker for Keep a Changelog development.
I recommend using rbenv or chruby to develop with Ruby. Docker is way too much
overhead (and power usage) on macOS to run something as simple as a middleman site.

While you have a greate Development section, it doesnt explicitely state anywhere that contributions are welcome. I have changed that with this redundant text.
