 ### Services
 
-This integration provides a service to modify the state of the `input_datetime`.
+Available service: `input_datetime.set_datetime`.
 
-| Service | Data | Description |
-| ----- | ----- | ----- |
-| `set_datetime` | `time` | This can be used to dynamically set the time.
-| `set_datetime` | `date` | This can be used to dynamically set the date.
+Service data attribute | Format String | Description
+-|-|-
+`date` | `%Y-%m-%d` | This can be used to dynamically set the date.
+`time` | `%H:%M:%S` | This can be used to dynamically set the time.
+`datetime` | `%Y-%m-%d %H:%M:%S` | This can be used to dynamically set both the date & time.
+
+To set both the date and time in the same call, use `date` and `time` together, or use `datetime` by itself. Using `datetime` has the advantage that both can be set using one template.
