=================
The *ExampleInterface* demonstrates creating custom interfaces for Reticulum.
Any number of custom interfaces can be loaded and utilised by Reticulum, and
will be fully on-par with natively included interfaces, including all supported

Custom Interfaces
=================
The *ExampleInterface* demonstrates creating custom interfaces for Reticulum.
Any number of custom interfaces can be loaded and utilised by Reticulum, and
will be fully on-par with natively included interfaces, including all supported
:ref:`interface modes<interfaces-modes>` and :ref:`common configuration options<interfaces-options>`.
