At its core, Cowpod is a pod mounting utility just like many others that have come before it. Place it in your mtm2 folder, double click it (or put a shortcut on the desktop) and you can easily add and remove track and truck pods from your game.
Note. If you do not know how to mount addons, then please see the beginners help page which you can find here.
Cowpod differs, however, from other pod mounting programs in many ways. Here are some of them.
