+CO2 concentration on a 4-digit 7-segment display and buzzer alarm when a high CO2 concentration is detected.
 
 ## Usage
 
-* Configure pin macro's.
+* Open [ErriezMHZ19B7SegmentDisplay.ino](https://github.com/Erriez/ErriezMHZ19B/blob/master/examples/ErriezMHZ19B7SegmentDisplay/ErriezMHZ19B7SegmentDisplay.ino).
+* Configure pin macro's and connect hardware.
 * Flash to target.
 
 Note: Wait at least 3 minutes warming-up time before valid plots are displayed.
