 ## Deploying firmware to the device
 
 Firmware can be deployed to the device by putting it into bootloader mode
-(hold down BOOTSEL while powering on or resetting) and then copying
-`firmware.uf2` to the USB mass storage device that appears.
+(hold down BOOTSEL while powering on or resetting) and then either copying
+`firmware.uf2` to the USB mass storage device that appears, or using

+conveniently via `make deploy`.
 
 If MicroPython is already installed then the bootloader can be entered by
 executing `import machine; machine.bootloader()` at the REPL.
