Installation
You can install wring using npm:
$ npm install --global wring
Wring utilizes PhantomJS for some of its commands. To use these, install it using your system package manager by running something like brew install phantomjs on OS X, or apt-get install phantomjs on Ubuntu. You can make sure it's on your PATH by running phantomjs -v.
Alternatively, you can install a version which automatically downloads PhantomJS binaries for your system:
$ npm install --global wring-with-phantomjs
