A page is a individual piece of content similar to a page on your website. Armadillo pages are separate from the pages created in RapidWeaver, since they are stored in an online database, rather than in the RapidWeaver project file on your computer.
Armadillo creates a dedicated menu for all of the pages you create in its online interface. You can choose to display these pages in that dedicated menu, or have Armadillo move the menu items to your site's native navigation area, so that they appear to be just like other menu items in the site navigation. For more information about how to do this, see the Primary Navigation menu article.
