 DESCRIPTION
 -----------
-The `lttng start` command starts the various LTTng tracers for a
-given inactive tracing session.
+The `lttng start` command starts a recording session, that is, it
+activates the LTTng tracers for:
 
-Starting the LTTng tracers has the effect that all enabled event rules
-within enabled channels can make their target event sources _emit_ trace
-events. Whether they are recorded to the local file system, sent over
-the network, or not recorded at all depends on the specific
-configuration of the tracing session in which tracing is started. See
-linklttng:lttng-create(1) for different session modes.
+With the 'SESSION' argument::
+    The recording session named 'SESSION'.
 
-A tracing session with running tracers is said to be _active_. Active
-tracing sessions can return to the inactive state using the
-linklttng:lttng-stop(1) command.
+Without the 'SESSION' argument::
+    The current recording session (see man:lttng-concepts(7) to learn
+    more about the current recording session).
 
-If 'SESSION' is omitted, the LTTng tracers are started for the current
-tracing session (see linklttng:lttng-create(1) for more information
-about the current tracing session). Otherwise, they are started for the
-existing tracing session named 'SESSION'. `lttng list`
-outputs all the existing tracing sessions (see linklttng:lttng-list(1)).
+See man:lttng-concepts(7) to learn more about recording sessions.
 
+The selected recording session must be inactive (stopped). A recording
+session is inactive on creation (see man:lttng-create(1)).

+A `start-session` trigger action can also start a recording session
+(see man:lttng-add-trigger(1)).
