You need nodejs and npm to install dependencies/build this project, and grunt/grunt-cli if you want to develop.
$ npm install
$ bower install
$ grunt
Instead of running grunt, run npm start instead on production.
Running grunt will make sure your front end assets compile when changed. In case the application is being run as root, run bower install --allow-root for installing the bower dependencies. This will create the sprinter/app/bower_components which will be used by grunt to compile the less files.
Your app should be running at http://localhost:1337
