Create New Units

I just download a Unit-editor, but I really don´t have any idea how to create own units, I know that there are now primary new, just modeled ones and there´s a spell editor, too. I think I know how to create new spells, but how to edit icons in Cast-list and how to bring the spells into the map-editor to give it to heroes?

Pls help a little n00b =) :ggani:

Plz read other forms. They will tell you all the stuff you need.

I don't use Unit-Editor, but in World Editor just put up the built-in unit editor and click "Create Custom Unit" and follow the steps.
