== How To Get It To Work ==
* Download the firmware on https://micropython.org/download/SEEED_XIAO/
* Enter boot-loader-mode by double pressing the reset-button (if there is no button just use a male-to-male wire and connect the two connectors like demonstrated in the video)
* Once the board shows up in your file manager copy the downloaded firmware-file from step one onto it (highest hierarchy)
* Open Thonny (or your preferred IDE) and go to Settings > Interpreter and choose the MicroPython (generic) interpreter. Make sure to choose the board as port (this may be different from system to system)
* That’s it! You should now be ready to start coding :)
