Insert the long legs of a six-pin ICSP male header into the smaller connector on the USBtinyISP.
Be sure the USBtinyISP's jumper is in place. Plug in your FLORA over USB and also connect your USBtinyISP to your computer over USB.

Connect the pins to FLORA as shown, using diagonal pressure to make good contact between the legs of the header and the ISCP pads on FLORA.


Select Adafruit Flora from the Boards menu.
Select USBtinyISP from the Programmer menu.
Hold the ICSP connector in place and click Burn Bootloader from the Tools menu. It will take a while, even longer than a minute. Sit tight and don't let go until the status reads Done burning bootloader. Congrats, you're done!
