vtm is based on [ngBoilerplate] (http://joshdmiller.github.com/ng-boilerplate), kickstarter for AngularJS projects.
Install Node.js and then:
$ git clone git://github.com/berkeley-gif/vtm
$ cd vtm
$ sudo npm -g install grunt-cli karma bower
$ npm install
$ bower install
$ grunt watch
Finally, open file:///path/to/vtm/build/index.html
in your browser.
Happy hacking!
