How do you add a new leader to a civilization? [Solved]

[DeepSoul]

I just want to replace the art of an existing leader with my own art, so I figured I could make a new version of the leader. Since you need a project for this I created a new mod in mudbuddy with the "New civilization and leader" template. I want to edit a french leader so I took all the files of a mod that adds Marie Antoinette, which comes with everything including config files, xlps and textures, and slapped them into the new project from inside modbuddy, then deleted all the files from the template. But I won't do anything else until the new mod works so I had to try it first. The build was successful but no new leader is added to France. How come?

If it's easier to just replace the art of Eleanor please describe how it's done, or if it's not too much trouble to make a working project of the one I uploaded it would be appreciated.

Edit: Solved. Needed to configure the project properties to load the necessary files. It's not easy for beginner modders.
