Install NVM
Install Node.js
Install NPM
We need to install two node packages to run them in command-line.
Install Grunt: run npm install -g grunt-cli
Install Bower: run npm install -g bower
Run npm install
(will install grunt-contrib-connect / grunt-contrib-watch / grunt-contrib-compass / grunt-contrib-jshint)
Run bower intall
Run grunt
and Grunt will automatically open http://localhost:9000/
When you modify anything, the page will refresh automatically.
