getting my fonts into...

I checked the FAQ for help with this, but I couldn't find what I wanted. So, I've downloaded some fonts from daFont.com, but now I have no idea how to get them into my Photoshop.

What do I do?

How do I make them an option whenever I use a font? If there's a tutorial on this or something I'd really like to know. I'm completely lost.

Please don't rag on me if this has been asked before. I really did look in the FAQ, and found something similer to my question. However it didn't help me one bit. u_u;
