+    <title>Description</title>
+
+    <para><function>sd_bus_start()</function> connects an existing bus connection object to the D-Bus
+    broker daemon, usually
+    <citerefentry project='die-net'><refentrytitle>dbus-daemon</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+    or
+    <citerefentry project='mankier'><refentrytitle>dbus-broker</refentrytitle><manvolnum>1</manvolnum></citerefentry>.
+    The mechanism to use for the connection must be configured before the call to
+    <function>sd_bus_start()</function>, using one of
+    <citerefentry><refentrytitle>sd_bus_set_address</refentrytitle><manvolnum>3</manvolnum></citerefentry>,
+    <citerefentry><refentrytitle>sd_bus_set_fd</refentrytitle><manvolnum>3</manvolnum></citerefentry>, or
+    <citerefentry><refentrytitle>sd_bus_set_exec</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
+    <function>sd_bus_start()</function> will open the connection socket or spawn the executable as
+    needed, and asynchronously start a <function>org.freedesktop.DBus.Hello()</function> call. The
+    answer to the Hello call will be processed later from
+    <citerefentry><refentrytitle>sd_bus_process</refentrytitle><manvolnum>3</manvolnum></citerefentry>. If
+    opening of the connection or queuing of the asynchronous call fail, the connection will be closed with
+    <citerefentry><refentrytitle>sd_bus_close</refentrytitle><manvolnum>3</manvolnum></citerefentry>.</para>
+
+    <para>In most cases, it is better to use
+    <citerefentry><refentrytitle>sd_bus_default_user</refentrytitle><manvolnum>3</manvolnum></citerefentry>,
+    <citerefentry><refentrytitle>sd_bus_default_system</refentrytitle><manvolnum>3</manvolnum></citerefentry>
+    or related calls instead of the more low-level <function>sd_bus_new()</function> and
+    <function>sd_bus_start()</function>. The higher-level functions not only allocate a bus object but also
+    start the connection to a well-known bus in a single function call.</para>
