Help

I guess i am just really slow or something that or the fact that its the middle of the night.
How do I actually use this module to do what I want.

I have a url
http://www.mysite.com/shop/index.php?main_page=product_info&products_id=36

and I dont understand about the go label or what to put where.
I want the url to be pointed to

http://www.mysite.com/shop/productname

Please help...!!!!
