If you don’t have them already, you’ll need the following:
$ npm install -g grunt-cli
$ npm install -g @11ty/eleventy
You’ll need to install GraphicsMagick for the automated responsive images. Homebrew is your best bet:
$ brew install GraphicsMagick
Then a spry npm install and you should be in business.
$ npm run dev will run both grunt watch and eleventy --serve. By default, the local dev server will pop up at http://localhost:8080, but your milage may vary—the URL will be in the output of running dev.
