+
+    <para><function>sd_bus_add_object_manager()</function> installs a handler for the given path
+    that implements the <function>GetManagedObjects()</function> method of the
+    <constant>org.freedesktop.DBus.ObjectManager</constant> interface. See
+    <ulink url="https://dbus.freedesktop.org/doc/dbus-specification.html#standard-interfaces-objectmanager">
+    org.freedesktop.DBus.ObjectManager</ulink> for more information.</para>
+
+    <para>To implement the <function>InterfacesAdded</function> and
+    <function>InterfacesRemoved</function> signals of the
+    <constant>org.freedesktop.DBus.ObjectManager</constant> interface, call
+    <citerefentry><refentrytitle>sd_bus_emit_interfaces_added</refentrytitle><manvolnum>3</manvolnum></citerefentry> and
+    <citerefentry><refentrytitle>sd_bus_emit_interfaces_removed</refentrytitle><manvolnum>3</manvolnum></citerefentry>
+    whenever interfaces are added or removed from the sub-tree, respectively.</para>
+
+    <para>When <function>sd_bus_add_object_manager()</function> succeeds, a slot is created
+    internally. If the output parameter <replaceable>slot</replaceable> is <constant>NULL</constant>,
+    a "floating" slot object is created, see
+    <citerefentry><refentrytitle>sd_bus_slot_set_floating</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
+    Otherwise, a pointer to the slot object is returned. In that case, the reference to the slot
+    object should be dropped when the object manager is not needed anymore, see
+    <citerefentry><refentrytitle>sd_bus_slot_unref</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
