Is there a definitive simple guide on how to add Kingdoms factions & units to M2TW?
I'm not looking to download anyone else's mod, but to add new factions to a mod that I've made myself.
(Basically, I'd like to add Ireland, Wales & Norway, and be able to build Templar & Hospitalier units when I go crusading.)

Specifics aside, which threads should I follow to add factions & units from Kingdoms packs to my mod?
Has a tutorial been written?

-oh, also, I'm not sure if anyone else has found this, but when playing, open the console and type in:
create_unit "character or city name" "Flemish Pikemen" 1 0 0 0
-NB, that's "Flemish Pikemen", not "Flemish Pikemen Mercs"
The unit doesn't have a skin - it'll appear like a silvery, ghostlike mass of pikemen. Looks rather spooky!
