+.. _bluetooth-hci-usb-sample:
+
+Bluetooth: HCI USB
+##################
+
+Overview
+********
+
+Make a USB Bluetooth dongle out of Zephyr. Requires USB device support from the
+board it runs on (e.g. :ref:`nrf52840dk_nrf52840` supports both BLE and USB).
+
+Requirements
+************
+
+* Bluetooth stack running on the host (e.g. BlueZ)
+* A board with Bluetooth and USB support in Zephyr
+
+Building and Running
+********************
+This sample can be found under :zephyr_file:`samples/bluetooth/hci_usb` in the
+Zephyr tree.
+
+See :ref:`bluetooth samples section <bluetooth-samples>` for details.
