After you have installed your theme, let's setup your Theme Options, which can be found at Appearance > Theme Options in your WordPress admin. Make sure to give these a thorough read-through so you know what you have control of from there. Theme Options allow you to configure and style different available areas of the theme such as fonts, colors, backgrounds, layout, sizes, Logo, and more.
Anything revolving the general appearance and functionality of the theme is controlled here. Keep in mind that a child theme can actually remove/add options to the main framework, Sweetness.
