coding help!

[fangy]

I'm new to v5. I made a proboards forum when it was still in v3, and I'm helping my friend make one. Truth is, this new system is mindboggling to me!

I have a premade skin I want to use but have no idea which admin feature to hit and apply it to the site! Steps would be so helpful! Please help! Thanks.

Here's the site:
demon-bound.proboards.com/

I wanna apply this skin:
