-    Plugin to interact with Bluetooth devices.
-
-    This plugin uses `_Bleak_ <https://github.com/hbldh/bleak>`_ to interact
-    with the Bluetooth stack and `_Theengs_ <https://github.com/theengs/decoder>`_
-    to map the services exposed by the devices into native entities.
-
-    The full list of devices natively supported can be found
-    `here <https://decoder.theengs.io/devices/devices_by_brand.html>`_.
-
-    It also supports legacy Bluetooth services, as well as the transfer of
-    files.
-
-    Note that the support for Bluetooth low-energy devices requires a Bluetooth
-    adapter compatible with the Bluetooth 5.0 specification or higher.
-
-    Requires:
-
-        * **bleak** (``pip install bleak``)
-        * **bluetooth-numbers** (``pip install bluetooth-numbers``)
-        * **TheengsDecoder** (``pip install TheengsDecoder``)
-        * **pydbus** (``pip install pydbus``)
