Help for the mod news

i'll add important events if requested by you. i may also add decisions like reforming the ROman Empire or uniting china conversion decisions may be added , there may be events from things that happen until 800 such as Islam and maybe the other forms of chrtistianity i would try to do some form of reformation event but that seems pretty hard. If someone knows how to make things like in eu4 for the reformation tell because that is very usseful for the spread of christianity , Islam the hussitte form of christianity and maybe many things more.In Order to create the mod i will need help from someone (or more ) that knows how to add units to the game , change the 3D units and someone who knows how to create Provinces. Now im going to continue saying how the units (land ones will be changed) Artillery = Cavalry = Knights/ Cuirassier = Cuirassier Dragoon = Armoured Soldier ( with shield) Hussar = Armoured Knight/ infantry = Soldier ( with spear or sword ) / irregular = archer / Engineer = Engineer / Guard = Noble Soldier / Tank = Tower / I may have to remove the plane because i don't have an idea for it.
