An online calculator for discounts in Brewdog bars for EFP's.
Pre-requisites: npm. Once you have npm installed, run:
$ npm install
And:
$ npm install -g grunt-cli
This will install Grunt, a task runner currently used to minify the JS code. Gruntfile is configured to run uglify on js/calculator.js to app.js which is linked in the index.html file. So if you change the source file (js/calculator.js), you need to run grunt in the command line for js/app.js to be rewritten and the page updated.
