              .when('/', {
                  templateUrl : 'home.html',
                  controller  : 'mainController'
              })
              .when('/about', {

                  controller  : 'contactController'
              });
      });
      scotchApp.controller('mainController', function($scope) {
          // create a message to display in our view
          $scope.message = 'Everyone come and see how good I look!';
      });
      scotchApp.controller('aboutController', function($scope) {
          $scope.message = 'Look! I am an about page.';
      });
      scotchApp.controller('contactController', function($scope) {
          $scope.message = 'Contact us! JK. This is just a demo.';
      });
  &lt;/script&gt;
  &lt;/head&gt;

      &lt;div id="main"&gt;
          &lt;div ng-view&gt;&lt;/div&gt;
