Are you starting a new site from scratch or are you adding this template to an existing site?
If you are building from scratch please use the QuickStart and install the demo data. This will give you a copy of the demo so you have a good starting point. You can just replace the data with your own.
If you are installing on an existing site it is more complicated. I recommend installing the QuickStart locally on your desktop. You can use tools like WAMP, XAMPP or MAMP on a mac. These tools creat a web server on your desktop so you can look through all the various setting and copy them to your live site.
