 ## Introduction
 
-A Mendix app consists of app-level documents and a number of modules. Each module can contain many documents. At the app level, there are some settings and documents that apply to your app as a whole. For example, navigation is an app-level document, and the menu bar is app-wide and can refer to functionality in all modules. However, most documents live at the level of a [module](/refguide/modules/).
