 # How to use a different vehicle
 
-## Select a different vehicle in Dreamview
-Enter Dreamview interface, click on the "vehicle" dropdown box in the upper right, and select a vehicle that you want to configure.
+To add a different Vehicle, you must first follow the [Readme Installation steps](https://github.com/ApolloAuto/apollo/blob/master/README.md) to assemble and launch Apollo successfully.
+
+In order to support a new vehicle in DreamView, please follow the steps below:
+
+1. Create a new folder for your vehicle under `modules/calibration/data`
+
+2. There is already a sample file in the `modules/calibration/data` folder named `mkz_example`. Refer to this structure and include all necessary configuration files in the same file structure as “mkz_example”. Remember to update the configuration files with your own parameters if needed. 
+
+3. Restart DreamView and you will be able to see your new vehicle (name is the same as your newly created folder) in the `Vehicle` dropdown menu.
+
+4. Select the newly configured vehicle.
