+### Via dfu-util
+
+This board can programmed via DFU bootloader, using e.g. [dfu-util](http://dfu-util.sourceforge.net/).
+To enter the DFU bootloader, double tap the reset (blue) button, or you can use `machine.bootloader()` from the MicroPython REPL.
+
+```bash
+dfu-util -w -a 0 -d 2341:035b -D build-ARDUINO_GIGA/firmware.dfu
+```
+
+Or from MicroPython source repository:
+
+```bash
+make BOARD=ARDUINO_GIGA deploy
+```
