The titles of each are rather self explanatory, but the basics:
1. Site title and tagline
2. Listings per page
3. Select from one of the 8 default color schemes
4. Upload a background image
5. Header and Footer menu selection
6. Front page displays settings
7. Category options for main page (e.g. category depth, subcategories shown, hide empty categories)
8. Category options for menu
Thanks.
