Step by step adding planes to mods?

[1Patriot-of-many]

Hey guys, is there a step by step guide to adding planes to a SF2 mod? I want to add some more modern planes to the Falklands mod in a what if scenario. What files need to be edited?  TIA

Check this in the SF2 Knowledge Base (A good place to check for some questions):
