1. First you'll need to download the Steam Engine.
2. Then you'll need a "Steam" Account if you haven't already done so. If not, click below, otherwise skip down to step #3.
Create Steam Account. Click here.
3. Once you've created an account you can download the game from the "Steam" site.
4. Once you have downloaded the game, launch the DRL Sim.
5. Now in the game click on your "Profile" on the bottom left of the main menu. From there you can change the color you'd like. The profile name and avatar image in the game is tied to which name/image you have on Steam or other platform you are playing from. You can change your steam profile name/avatar through Steam, reload the game, then the new name/avatar should be updated. If not, give it some time and it should update on its own.
You're all set!
