+
+Overview
+********
+
+The nRF52840-MDK USB Dongle is a versatile, easy-to-use IoT hardware platform for
+Bluetooth 5, Bluetooth Mesh, Thread, IEEE 802.15.4, ANT and 2.4GHz proprietary
+applications using the nRF52840 SoC.
+
+The kit features programmable user button, RGB LED, up to 12 GPIOs, antenna
+selection for custom applications.
+
+See `nRF52840-mdk-dongle website`_ for more information about the development
+board and `nRF52840 website`_ for the official reference on the IC itself.
