I suggest opening a simple mod up and looking at it while you're reading the modding.pdf. Unfortunately, there aren't that many "simple" mods, most add a nation, units into it and possibly even few national spells.

Weapon/armor modding is simple, but doesn't do anything before you add them to units via unit modding.

Unit modding basics aren't too complicated, but there's a huge list of available powers and abilities, and some of the commands are more complicated.

Nation modding is very simple, but you need unit modding to achieve anything.
