How to post a mod for BeamNG.com

Hi everybody!


I now turn to you with the question of how to post a for mod BeamNG.com.com? In fact, I finished the my first mod (in this case, the engine Covet 1.2) I can not account for, because he writes that "The uploaded file does not have allowed an extension." How could this get? The mod has been done, I do not want to help. The "modcreator" I'm going to make my career most configurations.

Thank you in advance for your help!

I was not thinking of how to do it, but also how to be exposing.
