I can't mod Skyrim

Okay so im completely new to the modding world, so bear with me, but i have absolutely no clue what im doing. all i know is i want to download a mod know as Apocalypse. i downloaded it from https://www.nexusmods.com/skyrim/mods/16225/?tab=files., downloaded the Horizon onto my computer, and now it keeps saying “invalid stsf package” someone help lol

Those mods can only be used on PC.

unless you have programs to make them as a jtag or rgh dlc look into it with modded warfare on his youtube page and he will give you the tools you need to make dlc out of pc mods
