+### My iOS App Can't Find Homebridge
+
+Two reasons why Homebridge may not be discoverable:
+
+  1. Homebridge server thinks it's been paired with, but iOS thinks otherwise. Fix: deleted `persist/` directory which is next to your `config.json`.
+
+  2. iOS device has gotten your Homebridge `username` (looks like a MAC address) "stuck" somehow, where it's in the database but inactive. Fix: change your `username` in the "bridge" section of `config.json` to be some new value.

+# Why Homebridge?
 
 Technically, the device manufacturers should be the ones implementing the HomeKit API. And I'm sure they will - eventually. When they do, this project will be obsolete, and I hope that happens soon. In the meantime, Homebridge is a fun way to get a taste of the future, for those who just can't bear to wait until "real" HomeKit devices are on the market.
