 The Sonoff RF needs some tweaking as the connection needed during programming between the button and GPIO0 might not be present.
 
-This connection *must be removed* after the conversion to Tasmota or a button press will send the device in an ON/OFF loop.
+This connection **must be removed** after the conversion to Tasmota or a button press will send the device in an ON/OFF loop.
 
-This can be achieved by shorting both solder pads of *R21* with a small screwdriver while holding down the button during programming. This can be a bit fiddly, and ideally you should check the bootloader output over serial to see whether you managed to get it into programming mode. Alternatively, [Phalox](http://phalox.be/wp/electronics/itead-sonoff-slampher-custom-firmware-fix/) installed a jumper wire (explained in the picture below). Remember to remove it after programming.

-The R2 V1.0 version of the Sonoff RF uses an ESP8285 which is covered by a horizontally orientated RF expansion board. Entering flash ready mode can be achieved by grounding K_P (which is connected to GPIO0) to the neighbouring GND pin on the RF board during power on. https://imgur.com/a/rJ3zGQQ

 - two short button presses will blink a red led shortly and start RF signal recognition. Three longer blinks signal RF reception.

-### Procedure
+### Pairing Instructions
 Pairing the iTead RF remote controller is the same as with the original iTead software:
 - two short button presses will blink a red led shortly and start RF signal recognition. Three longer blinks signal RF reception.
 - three short button presses will keep the red led on for some seconds and erase the known RF code. 
 
 I was unable to pair the Sonoff RF 434MHz receiver with my KaKu switches but the iTead provided remote control works just fine.

+## Version 2 Pairing Instructions
 RF units produced after 6/2018 use a different procedure for pairing. 
 
 - Press and hold the button for 3-seconds until the red light flashes once, then press then button on your remote to program. 
 - Press and hold for button for 5-seconds until the red light flashes twice to clear remote programming.
