Thats it. I have my mod running (I copied another mod as a test.)

Its in its own mod folder and it shows up in Steam and it runs from the menu.

I've extracted the .u file and theres now a folder called Classes in my mod folder. I want to modify those files.

When I delete the .u file and modify the .uc files in the classes folder, how do I complie them into a .u?
