Please help me Create a mod

[Primitive1]

Hey people,

I wanted to create a mod, I want to edit the missions in Men of War and turn them into missions of my own. But I don't know how to do that because I created everything in mods folder and put the files in it but it replaces the missions. I don't want to replace the missions, I want them to be new ones like the ones I downloaded from the internet. Can anyone please help me create my own mod? Thanks.
