you have to unzip quickstart package, and transfer files via FTP (wp-admin,wp-content, wp-themes and rest unzipped files) to your public_html directory (then you have to enter e.g. this URL
http://www.yourdomain.com), if you want to use e.g. this URL
http://www.yourdomain.com/subdomain, upload your files to public_html/subdomain directory..
It's the same process like standard WordPress instalation.
