Removing Category Menu bar

Hello,

I recently purchased this theme but have no need for the Categories to be listed as if they were a menu at the top of the page. How can I remove this bar?

Ideally I would like it to be replaced with the menu bar for my pages rather than categories.

Thanks,

-Steve.

Hi!
By default, there are two menus always visible on your screen, the "Main" menu and the "Top" menu. To customize any of them you have to go to the page Appearance => Menus and set the created menu as a main/top menu. Here are the intelligible instructions:
