The sample demo of the angular ui router has this link for the start page:
full url of \'ui-router\' is / or http://angular-ui.github.io/ui-route
use the $urlRouterProvider and its otherwise function:
angular.module('MyApp', ['ui.router'])
.config(['$stateProvider', '$urlRouterProvider', function ($stateProvider, $urlRouterProvider) {
$stateProvider.state('default', {
controller: 'MyController',
templateUrl: 'path/to/template.ng.html',
url:'/default'
})
$urlRouterProvider.otherwise('/default')
})];
