//create a Backbone Router
var myRouter = new Backbone.Router();

//create a help route using route method, route(route, name, callback-function)
    console.log('The url hash just change to /#help');

//change url hash to "#help", but Backbone does nothing
window.location.hash = 'help';

//tell Backbone to start listening for changes in the URL

//change url hash to "#help", now routes work!
window.location.hash = 'help';
