if i have exported the mod, and i have the mod folder, does it not have a descriptor file? can someone please explain to me how i could export the mod? do i have to copy the code or do i just place the file somewhere?

1st - export the mod

2nd - copy all the common, gfx, history files (inside on the file with named numbers [dont need to copy file with numbers, just copy all  things on the inside])

3rd - paste all the things on the your hoi4-mods file.

Step by step here from Underfoxy

So first you go to your launcher, go to "All installed Mods" and Click on "Upload Mod" on the Top Right of the Launcher. Then a screen should pop up where you click on "Create Mod". After that a new screen should appear. Type in your name, Version (best is 0.1) and type in your name how it should be called in the folder. At last you have to select some keywords and click "Create Mod".

After that you have to go to your Documents Folder and search for "Paradox Interactive" and in that for "Hearts of Iron IV".

In that folder you have to search for "mods". In there you should see your folder you just created in the launcher. Open your Mod you created in this Browser and drag and drop the folders (the folders in the folder in the zip)  in the folder you created in the launcher. So now you can close everything and play your mod. Hopefully its not that complicated. It's just hard to explain.
