Using the resource

The Car Sale Sign resource adds the ability to put a price tag inside the vehicle.

After getting into the vehicle you wish to install this sign you want to run the command /salesign install

Once you have run the command a sign will appear in the bottom right of your screen. You can use the arrow keys to change the character in each slot; the up arrow moves up the character list, and the down arrow moves down the list. The left and right arrow keys allow you to change the slot on the sign. Once you've selected your characters, you can press enter to spawn the sign in the vehicle.
