How to make use of specification attributes?

I am a new user to Nopcommerce.
I lised some products to our site based on this systems.
But I do not know how to let the specification attributes set up show on the products pages.
Can anyone tell me how to let these attributes show on my products pages?

Review the notebook computers on the demo site http://demo.nopcommerce.com/p/11/asus-eee-pc-1000ha-10-inch-netbook. The product above has specification attributes displayed and it is configured on this page http://admin-demo.nopcommerce.com/Admin/Product/Edit/70.

You can reverse engineer the configuration above to learn how it applies to your products and create specification attributes as needed.

Hi.
Thanks for your reply.
I try to set up the specifications attributes as the same way of demo site.
But it still does not show out.
Can u tell me what the problems may be? Should I set up som other things?

I had the same problem in the live site. In demo site in my computer works fine since i have selected to install sample products during the installation. But in the live site I did not select to add sample data.
So I found that It is required to add atrributes before adding the products. You can access it from the admin site:
Catalog > Attributes >
