N00B Question - Mods with Options Question

[Genadine]

Hi,

 

Firstly a big thanks to all the Modders for their time and effort to improve Skyrim and in some cases fix it.

 

My question which will no doubt have a few people in hysterics but here goes.

 

 

I use NMM religously to install all my Mods, but I see version conflicts when a Mod has Optional parts, for instance the Coolsims hair mods, lots of ways to do this but which is correct, do I install the original then overwrite or upgrade with the Options?

 

 

Thanks for any response.
