+OpenThread support in Oniro
+***************************
 
-You can connect the Thread network to the internet using the Thread Border Router. 
-The Thread Border Router is an open-source implementation provided by the 
-OpenThread community.

+The OpenThread open-source project offers a few key components needed to
+operate in a Thread network. The core protocol implementation can run on
+bare-metal, RTOS or Linux, depending on your use case. Oniro supports
+running a Thread node on the Zephyr flavour and a full border router on
+the Linux flavour. The following four targets can be build with bitbake and the
+Oniro layers:
+
+* OpenThread Border Router (bitbake ot-br-posix)
+  A fully fledged border router configuration where you have at least one Thread
+  network interface and an additional one to other networks (e.g. Wi-Fi or
+  Ethernet), and optionally an internet uplink.
+
+* OpenThread posix service (bitbake ot-daemon)
+  For a use case where the device only wants to join a Thread network, but does
+  not need to have full border router capabilities. The ot-daemon service runs
+  on Linux and offers a standard Linux network interface e.g. `wpan0` to operate
+  on.
+
+* Radio Co-Processor firmware (bitbake zephyr-openthread-rcp)
+  For the border router configuration, a radio interface is needed to communicate
+  with the Thread network. The hardware could be the usual Arduino Nano 33 BLE or
+  a USB dongle with the same SoC as the Arduino Nano 33 BLE. To work with the
+  OpenThread Border router on the Linux side this special firmware neededs to be
+  flashed to the radio device.
+
+* OpenThread node on Zephyr (bitbake zephyr-blueprint-gateway-node)
+  The node target is only available if the build includes the Oniro blueprint
+  layer. This example application configures various details needed to run
+  OpenThread on Zephyr. It can be used as the base for developing an application.
+
+None of the components is part of the default images provided by Oniro. To add
+them to your custom image, you would need to define a custom image recipe, or append
+to `local.conf` something similar to:
+
+.. code-block:: console
+
+        IMAGE_INSTALL:append = " ot-br-posix"
+
+Oniro Blueprint with OpenThread
+*******************************
+
+To demonstrate a turn-key solution with an OpenThread Border Router on Linux,
+as well as an OpenThread node based on Zephyr, Oniro implemented a `Transparent
+Gateway Blueperint
+<https://docs.oniroproject.org/projects/blueprints/transparent-gateway.html>`__.
+In the blueprint documentation you can find more details on building and flashing
+the components and on-boarding the device with a mobile application.
