This probably has a stupidly easy answer, but I'm unable to find it in the forum. So:

I'm jusdt now beginning to get my feet wet with the creation kit, starting to make a new custom follower. I think I have that process sussed out, but what I want to do is make sure that new follower is available on both my big desktop here at the house and on my travel laptop.

Once I have the new follower NPC working on my main machine, which files do I need to copy over to the laptop so my new follower is available when I'm on the road?
