 ### Folders structure
 At the top level, the repository is split into a client folder and a server folder.  The client folder contains all the client-side AngularJS application.  The server folder contains a very basic Express based webserver that delivers and supports the application.
 Within the client folder you have the following structure:
-* `build` contains build tasks for Grunt
+* `node_modules` contains build tasks for Grunt along with other, user-installed, Node packages
 * `dist` contains build results
 * `src` contains application's sources
 * `test` contains test sources, configuration and dependencies
