Help, need "Dummy" guide to modding

[dummy]

We have the full Version, and we look forward to the opportunity to create some mods.

That said, we have read the mod user manuals included with the game. Now, that being said, could I please have someone explain in ENGLISH how to mod.

Our eyes glazed over while reading the manuals, which I am sure are great, if you know or have some preexsisting experience with modding.

We have none.

We are still at a loss on how to make a map, let alone set up DO to have some kind of tile editor in game (the mod manual makes refrence to inserting some "-tilegen" somewhere, but I have yet to find the magic spot that makes this happen)
We try to use the included editors- that let you select the tile pieces, but I fail to see how to take that to the next step.

PLEASE PLEASE PLEASE could someone simply give a step by step instruction on how to make a map, change the map, add monsters, add items, etc?

How hard would it be to just make a program that allows you to "paint" the maps, or setions of maps, in the game (think of it like a map editor from some civ games)?

I have yet to figure out how to make a "15 by 15" square since all I can seem to do is make single squares in an editor that are layered.

In a word, HELP.

please.
thanks.
