 **A demo app for the iBeacons API in iOS 7**
 
-HiBeacons is a fully functional demo app for the new iBeacons API in iOS 7. The app can be used to demonstrate both beacon advertising and ranging, by toggling on/off two switches. You can easily see any beacons in the vicinity, with all their info, under the 'Detected Beacons' section.

 ## Notes
 
-- The app can only monitor a single beacon region, but can easily be extended for multiple.
+- Monitoring works when the app is in the background. You will get a local notification when entering a beacon region.
+- The app can only monitor and range a single beacon region, but can easily be extended for multiple.
 - You can find and set the UUID and identifier for the beacon (and the region) at the top of NTViewController.m. 
 - Major and minor integers are generated randomly every time a new advertising session starts. 
 - The app will not list itself as a beacon, even if you toggle advertising on. (It's how the API works.) You need to run another instance of the app for that.
