-    proxy to a given D-Bus endpoint.</para>
+    <para><command>systemd-stdio-bridge</command> implements a proxy for a D-Bus endpoint. It expects to
+    receive an open connection to a bus when started, and will also connect to a (different) bus as a
+    client. It will then act as a server on the first connection, and forward messages between the two
+    busses. This program is suitable for socket activation: the first connection may be a pipe or a socket
+    and must be passed as either standard input, or as an open file descriptor according to the protocol
+    described in
+    <citerefentry><refentrytitle>sd_listen_fds</refentrytitle><manvolnum>3</manvolnum></citerefentry>. The
+    second connection will be made by default to the local system bus, but this can be influenced by the
