@@ -9,3 +9,5 @@ Raspberry Pi Pico has a BOOTSEL mode for programming firmware over the USB port.
 A drive called RPI-RP2 should pop up. Go ahead and drag the desired `*.uf2` file onto this drive. This programs the firmware onto the flash memory on your Raspberry Pi Pico. It should take a few seconds to program the UF2 file into the flash. The board will automatically reboot when finished, causing the RPI-RP2 drive to disappear.
 
 > **Note:** If you are not following these instructions on a Raspberry Pi Pico, you may not have a BOOTSEL button. If this is the case, you should check if there is some other way of grounding the flash CS pin, such as a jumper, to tell RP2040 to enter the BOOTSEL mode on boot. If there is no such method, you can load code using the Serial Wire Debug interface.
