Zuul is installed via npm. While zuul is written in node.js, your project doesn't have to use any node.js to benefit. In fact, zuul can easily be used to test ember.js, angular or other larger projects.
To install zuul for use during development simply run the following
npm install -g zuul
This will install zuul globally and make the zuul command available on the command line.
Once you have installed zuul, verify it works by going to one of the examples (in the examples folder) and running zuul.
zuul --local 8080 -- test
Open the url zuul shows and see the tests run. That's it! You are now ready for the quickstart guide to write your first tests.
