+## Bootloader
+
+The Corne PCBs have a reset button next to the TRRS jack to enter in to the bootloader.
+
+Additionally, if you hold down the "Q" or "P" buttons when plugging in that half of the keyboard (per the default QWERTY layout), this will jump to the bootloader and reset the EEPROM (persistent storage).  This would normally be the very top corner-most position, but due to the breakaway column, it's left at Q and P for compatibility. 
+
 ## RGB Matrix 
 The Corne Keyboard also supports using the RGB Matrix feature, in place of RGB Light.  This provids a better experience when using the keyboard, as it supports a number of per key effects properly.  If you're not using the in switch LEDs, then you may want to pass on doing this.
