Connecting the dots with Menus:
In each theme you can edit the primary links that are the navigation pointers for visitors on your site. You can edit the primary links for your theme from Administer » Site building » Menus. You can add as many menu items as your theme allows you to display. You can control the order of a menu items on your list by altering the assigned weight. Menu items with -10 will move to the left and +10 move to the far right. The path variable controls the location or URL a person is directed to when a specific menu item is clicked.
The content you create with specific URL name can be listed here to create a link or navigation pointer to the main items your site is about.
Additionally you can create separate menu items and link them in other areas of your theme such as the footer. You can use tagging to create dynamic pages that get updated as new content is created. This will become easier to understand after the taxonomy chapter.
In this video you will see how to create a primary menu and connect URLs (paths) to it.
