Once license plate blueprint is created, we also need to create modinfo for the mod. This process is the same as for other mods. Simply select Bus License plates and type in all the details and pick the correct class. It is crucial to have unique ID (top textbox) from any other existing mod. The license plate display text is then displayed in the UI while customizing, so it is also recommended to be filled out.
Once done cook the mod and copy to game directory (or make a zip file that can be uploaded to mod.io)
