 This is also a new feature which allows you to add context information to an
 event. For example, you can add the PID along with the event information:
 
-# lttng add-context -k -e sched_switch -t 0
+# lttng add-context -k -e sched_switch -t pid
 
 At this point, you will have to look at 'lttng add-context --help' for all
 possible context type which are integer values.
 
 You can on the same line activate multiple context:
 
-# lttng add-context -k -e sched_switch -t 0 -t 2 -t 4
+# lttng add-context -k -e sched_switch -t pid -t nice -t tid
 
 5) Enable perf counter for an event:

 You'll have to use the add-context help for all possible perf counter values.
