-By default, the man:lttng-create(1) command automatically spawns a
-user session daemon if none is currently running. The
-option:--no-sessiond general option can be set to avoid this.
+If your Unix user is not `root`::
+ If your Unix user is part of the Unix tracing group:::
+ Try to connect to the root session daemon.
++
+If the root session daemon isn't running, connect to the session daemon
+of your Unix user.
+
+ If your Unix user is not part of the tracing group:::
+ Connect to the session daemon of your Unix user.
+
+The name of the Unix tracing group is one of:
+
+With the nloption:--group='GROUP' option of the root session daemon (man:lttng-sessiond(8))::
+ 'GROUP'
++
+In that case, you must use the option:--group='GROUP' option, with
+the same 'GROUP' argument, of the `lttng` tool.
+
+Without the nloption:--group option of the root session daemon::
+ `tracing`
+
+LTTng-instrumented user applications automatically register to both the
+root and user session daemons. This makes it possible for both session
+daemons to list the available instrumented applications and their
+instrumentation points (see man:lttng-list(1)).
