To install :

use OpenIV > Navigate to jogger.ytd (Or joggerpas.ytd, whichever you choose to put the liveries on) > Open the .ytd in edit mode, Import the .dds livery file(s) of your choosing > Replace "YourNumberHere#" With a normal number that is above the ammount of liveries you have > Save

Your livery should be named "Jogger_sign_5" or whichever number you decide to place, if you do not replace the text with just a number the livery will not work

If you have two liveries with the same name, they will not work
