+Writing an invoice transmission plugin
+======================================
+
+An invoice transmission provider transports an invoice from the sender to the recipient.
+There are pre-defined types of invoice transmission in pretix, currently ``"email"``, ``"peppol"``, and ``"it_sdi"``.
+You can find more information about them at :ref:`rest-transmission-types`.
+
+New transmission types can not be added by plugins but need to be added to pretix itself.
+However, plugins can provide implementations for the actual transmission.
+Please read :ref:`Creating a plugin <pluginsetup>` first, if you haven't already.
+
+Output registration
+-------------------
+
+New invoice transmission providers can be registered through the :ref:`registry <registries>` mechanism
+
+.. code-block:: python
+
+   from pretix.base.invoicing.transmission import transmission_providers, TransmissionProvider
+
+   @transmission_providers.new()
+   class SdiTransmissionProvider(TransmissionProvider):
+       identifier = "fatturapa_providerabc"
