 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.
 
-[Phalox](http://phalox.be/wp/electronics/itead-sonoff-slampher-custom-firmware-fix/) explains the case with a picture where you have to install a jumper wire for R21. I received the same result using a small screwdriver and shorting both solder pads of R21 while holding down the button during programming.
+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.
