There are two ways that you can create a driver in Delivery. Users can create either through "舰队名单" 或 “Delivery”.

FLEET LIST

1. In Fleet Map, go to “List” then Drivers.
2. On the top right select "增加司机".
3. Input the necessary details. Toggle Delivery to be enabled to have the driver access to Driver App.
4. Driver needs to input a Driver App PIN. This will be used for the Driver to access on the Driver App.
5. 選擇 "增加司机".

筆記： 
If the driver has already been created, you can just select the driver and toggle the Delivery option to be enabled in the Delivery tab in List > Drivers.
