+    </para>
+    <para>
+      Plugins will provide their own Modem object implementations, usually subclassing the
+      generic <structname>MMBroadbandModem</structname> object. As previously explained, this
+      object implements every interface that may be exported by the Modem object in DBus; and
+      then, depending on the per-interface support checks, the interface will end up being
+      really exported or not.
+    </para>
+    <para>
+      Each interface defines every step to be run during the initialization, enabling or
+      disabling sequences. Then, the object implementing the interface may or may not provide
+      the implementation of such step. By default, the generic
+      <structname>MMBroadbandModem</structname> object implements already most of the steps
+      in the interfaces providing common features:

+    <para>
+      Vendor-specific subclasses of <structname>MMBroadbandModem</structname> are then able to
+      either provide their own implementation of a given step (in the image below, a custom
+      implementation for capabilities checking); or even completely disable the step if they
+      know that there is no way to run it (in the image below, revision string loading is
+      removed).

+    <para>
+      These subclass-able steps are all implemented as standard GIO asynchronous functions,
+      so subclassing a step involves implementing both the async method which receives the
+      input arguments to the action and the corresponding <literal>_finish()</literal> method
+      which provides the results of the action once the operation is ready.
+    </para>
+    <para>
+      It is worth noting that these steps and the asynchronous methods implementing them
+      don't assume that an AT port will be used to implement the real action. This means
+      that any other kind of port may be really used (e.g. QCDM or QMI) in the implementation,
+      or even that a static reply can be returned (e.g. Iridium modems will always report
+      "Iridium" as current OperatorName).
