What should I do for Scripts?

Umm. Hello there.
I just got Scar and a lot of scripts.
Can someone teach me how to use the scripts for scar?

I really need to learn.
WHen i tried one tutorial, it kept on saying error in line 1?
I did all of the thing, but I couldn't do it.

Also, I heard that i had to download something called the srl?
Can someone tell me which website to go to for tuts or where to download the right srl?

I really need help.
Thanks.
