 Building Micropython
 --------------------
-Prior to building the Micropython firmware, we must first generate a tarball

-to generate this file.
 
-After cloning the Micropython firmware, change directory into `firmware/micropython/ports/stm32`
-and run the command `make BOARD=DCFURS_F411 FLASH_TARBALL_FILE=../../../../dc26-fur-scripts.tar.gz`
