+### Date/Time Dialog Service
+ 
+You can also use the Date Time picker as a service, using the `mdcDateTimeDialog` service. The dialog returns a promise which is resolved with the selected date-time value and rejected on cancellation. 
+
+Example usage: 
+
+```javascript
+    someModule.controller('DemoCtrl', function ($scope, mdcDateTimeDialog) {
+
+      $scope.displayDialog = function () {
+        mdcDateTimeDialog.show({
+          maxDate: $scope.maxDate,
+          time: false
+        })
+          .then(function (date) {
+            $scope.selectedDateTime = date;
+            console.log('New Date / Time selected:', date);
+          }, function() {
+            console.log('Selection canceled');
+          });
+      };
+    })
+```
+
+The `mdcDateTimeDialog.show` accepts the same options as the directive. 
+
+```javascript
+     {
+       date: {boolean} =true,
+         time: {boolean} =true,
+         format: {string} ='YYYY-MM-DD',
+         minDate: {strign} =null,
+         maxDate: {string} =null,
+         currentDate: {string} =null,
+         lang: {string} =mdcDatetimePickerDefaultLocale.locale,
+         weekStart: {int} =0,
+         shortTime: {boolean} =false,
+         cancelText: {string} ='Cancel',
+         todayText: {string} ='Today',
+         okText: {string} ='OK',
+         amText: {string} ='AM',
+         pmText: {string} ='PM'
+     }
+```

+## Important Note on Using Locales
 
 Please see this [issue](https://github.com/logbon72/angular-material-datetimepicker/issues/51). To use a locale with your date time picker dialog, you'll have to include the moment.js locale file.
