 # File structure
 This project is organized around a 'module' / 'component' architecture. 
 
-By 'module', we mean anything that has it's own database collection and one or more routes. Components are more closely related to the idea of [WebComponents](http://webcomponents.org/), which are intended to be reusable, hierarchical user interface elements.
-
-In general, our file structure follows this pattern:
-
-* **/ (project root)**
-  * **module_name/**
-    * **collection/**
-      * *index.js*
-      * *schema.js*
-      * *permissions.js*
-      * *helpers.js*
