 In addition, MCU driver submodule is also needed to provide low-level MCU peripheral's driver. Luckily, it will be fetched if needed when you run the ``make`` to build your board.
 
+Some modules will also require a module-specific SDK (e.g. RP2040) or binary (e.g. Sony Spresense) to build examples.

 Note: some examples especially those that uses Vendor class (e.g webUSB) may requires udev permission on Linux (and/or macOS) to access usb device. It depends on your OS distro, typically copy ``/examples/device/99-tinyusb.rules`` file to /etc/udev/rules.d/ then run ``sudo udevadm control --reload-rules && sudo udevadm trigger`` is good enough.
