How to install script?

Hi all,

I have downloaded a website template but I don't know how to install it. These are what comes in the zipped folder: style.css, images folder,http://www.webmaster-talk.com/#file. Do I just upload the files to my web host through ftp?
I have only used wordpress and blogspot before.

Please kindly provide me with the steps to edit and install a free website template. Thanks.
