+### Bootloader script
+This Python script interacts with the ST ROM bootloader to erase and write a new firmware image.
+To use it, you will first need to place the unit into DFU mode by sending the "dfu" command from the CLI. Don't forget to disconnect your serial terminal first.
+
+Alternatively, the script could be modified to send the "dfu" command, then re-connect with even parity enabled and engage the bootloader.
