+    <title>Description</title>
+
+    <para><function>sd_bus_set_server()</function> configures the bus object as a server for direct
+    D-Bus connections. <parameter>b</parameter> enables/disables the server mode. If zero, the
+    server mode is disabled. Otherwise, the server mode is enabled. Configuring a bus object as a
+    server is required to allow establishing direct connections between two peers without going via
+    the D-Bus daemon. <parameter>id</parameter> must contain a 128-bit integer id for the server. If
+    clients add a guid field to their D-Bus address string, the server id must match this guid or
+    the D-Bus authentication handshake will fail. If no specific id is defined for the server,
+    <citerefentry><refentrytitle>sd_id128_randomize</refentrytitle><manvolnum>3</manvolnum></citerefentry>
+    can be used to generate a random id instead.</para>
+
+    <para><function>sd_bus_get_bus_id()</function> stores the D-Bus server id configured using
+    <function>sd_bus_set_server()</function> (for server bus objects) or received during
+    D-Bus authentication (for client bus objects) in <parameter>id</parameter>.</para>
