+## Proton C Conversion Guide
+
+If you're one of the lucky people to have Proton Cs to use with their Kyria, there are a couple of caveats to getting this working.
+
+1. You need to have 2x Proton Cs, as you cannot mix and match with Pro Micros or Elite C's.  They both need to be Proton Cs.
+2. You'll need to do some modding to enable proper support with the Proton C.
+
+By design, the Kyria uses every available pin on the Pro Micro footprint.  This includes using D3 (RX) for RGB.  This poses a challenge with using the Proton C, since it needs both the TX and RX pins. The Proton C needs both pins, especially if you plan on using Full Duplex Serial. 
+
+To fix this, you need to break off the last header position on the right-hand side on the footprint. This is the `TX0/D3` pad. Leave this pad without a header connected to.
+
+From the A9 pin on the Proton C, you want to run a wire from it to the `SDA + Extra Data` pad near the TRRS jack on the PCB. This will allow for proper, full duplex communication over the TRRS cable. 
+
+To get RGB working properly, as well, you want to run a wire from the `A3` pin on the Proton C, next to the GND and DFU pin, right under the USB port.  Run this to the `TX0/D3` pad (the one you left without a header pin on the PCB).
+
+Once you've done that, you can solder in the Proton C. and flash it.
