Setting up jQuery

Oh, the pain of trying to implement a pre-made script from the internet when you don’t understand how it works! I used to go through this all the time –  I’d find someone’s plugin for a sweet jQuery carousel or lightbox or hover effect, but I didn’t understand enough code to figure out what I was doing wrong, and get it working.

If you’ve ever experienced this bang-your-head-against-a-wall frustration, I hope I can fill in some of the blanks for you.
