JasmineJ143 on "How to clear or create new database for existing URL"

Hi,

I've just purchased a new theme and the first instruction is: Install Wordpress (Check your hosting provider, these days there’s often the option to 1-click-install. Don’t install this over a pre-existing database or site. This is a must, you can’t port over old WP installs or databases as our structure is different.)

I want to keep my URL but I am happy to delete all content, is this what the theme requires me to do? How do I reset or create a new database for my website to install this theme?

I am with GoDaddy
