This document summarizes key principles of usability and web site navigation from Steve Krug's book "Don't Make Me Think". It discusses the importance of clearly identifying the site, page title, main sections and navigation options on a site's home page. The footer and secondary navigation should also be clear. Internal site pages should maintain consistent primary navigation while allowing flexible page designs. A search box is typically included in the upper part of the page.

14. Krug’s “trunk test”
• What site is this? (Site ID)
• What page am I on? (Page name/heading)
• What are the major sections of this site?
(Sections)
• What are my options at this level? (Local or
secondary/tertiary navigation links)
– Or, where can I go from here?
• How can I search?
