First, you need to play your game and see if it's working. If you find:
Exclamation Marks, which represents missing meshes.
That your game is bugged out.
Nothing in the game that is part of the mod.
When you load a save, it firsts tells you content isn't available before continuing.
If you find any of these things, then you haven't installed the mod correctly. Try to reinstall the mod and read the instructions carefully, then when it's done go play your game to see if it was installed correctly. Remember, this mod has a lot of stuff such as creatures, NPCs, new armor, new weapons, so it'll be easy to notice. If you installed the mod correctly, and it works, then good gaming!
