 # CoreTemp display
 
-Basic bare-bones example of connecting to a bluetooth [CoreTemp](https://corebodytemp.com/) device and displaying the current body core temperature readings.
+Basic example of connecting to a bluetooth [CoreTemp](https://corebodytemp.com/) device and displaying the current skin and body core temperature readings.
 
 ## Usage
 
-On startup connects to a CoreTemp device (1809/2A1C) and emits a "Core, temp" value for each reading.
-The app simply displays these readings on screen.
+Background task connects to any CoreTemp device (2100/2101) and emits a CoreTemp signal value for each reading.
+Application contains three components, one is a background task that monitors the sensor and emits a 'CoreTemp' signal on activity if activated in settings.
+The widget shows when the sensor is enabled with a mini value and blinks on use.
+The app listens for 'CoreTemp' signals and shows the current skin and core temperatures in large numbers.
 
 ## TODO
 
 * Integrate with other tracking/sports apps to log data.
-* Add device selection
-* Provide enable/disable option
-* Check status, add Retry/reconnect
-* Also provide skin temp reading
+* Add specific device selection
