 +==== Installation ====
 +
 +To add Seeeduino XIAO to Arduino IDE add in file/preference the following URL to the Additional Boards Manager URLs:\\
 +  https://files.seeedstudio.com/arduino/package_seeeduino_boards_index.json
 +Than search and install in tools/boardmanager these boards:\\
 +  Seeed SAMD Boards
 +
 +On Arch Linux it needs always two attempts to upload the code, the /dev/ttyACM0 can't be opened: **No device found on ttyACM0**!\\
