For markings... put all of the markings in your textures folder. And then open up markings.cfg (the one that came with the download) and copy everything inside of it.
Go to FeralHeart and YOUR markings.cfg and paste the codes below all of your other markings.
Presets... If you want to see your friend's persets, then put the one file in Presets. (Not My_Presets.) If you downloaded a wearable preset, then put it in My_Presets. :)
Hope this helped!

I didn't download any yet, but I will try to find out more, I dont know why I didn't look in the part where members tell how to do things, I feel stupid now
You're not stupid. Even I can't find things that are right in front of my eyes. xD You just want answers, so you asked. That's okay. At least someone didn't post the same question ten seconds ago. Lol. Don't feel that way about yourself. -Nuzzle- c:
