right now the README just says "rundocker-compose up", but I found that on my MacOS 10.14 laptop, I needed to do the following:

• brew cask install VirtualBox docker
• brew install docker-machine docker-compose
• docker-machine start
• eval $(docker-machine env)
• docker compose up

and then later, if I want to shut it down,

• docker-machine stop

this is probably routine stuff for those familiar with Docker, but some of us are about as ignorant of Docker as we are of Ruby and Bundler :-)

the above commands seemed to work, and what I saw in my terminal window ended with:

jekyll_1  | Configuration file: /site/_config.ymljekyll_1  |             Source: /sitejekyll_1  |        Destination: /site/_sitejekyll_1  |  Incremental build: disabled. Enable with --incrementaljekyll_1  |       Generating... jekyll_1  |                     done in 29.876 seconds.jekyll_1  |  Auto-regeneration: enabled for '/site'jekyll_1  |     Server address: http://0.0.0.0:4000

the readme says the site will be served athttp://localhost:8080, but it isn't. I'm not sure why, perhaps it's because I'm on MacOS and not on Linux (except via VirtualBox)? how do I view the site? (visitinghttp://0.0.0.0:4000 doesn't work either)
