-Currently add a lttng trace provider and add tracepoint into object instances.
+Currently add a lttng trace provider and add tracepoint into object instances and destructions.
+
+The lttng nit/misc/Nit_Compiler.lttng file is a template that you can use instead of configure channels by yourself. You have to configure the path of the destination tracefile. <destination> <path> "your path" </path> </destination>
+
+To create a channel with template :
+       lttng-sessiond --daemonize
+       lttng load -i=~/nit/misc/Nit_Compiler.lttng Nit_Compiler
+To create a channel without template :
+       lttng create session_name
+       lttng enable-event --userspace Nit_Compiler:Object_Instance
+       lttng enable-event --userspace Nit_Compiler:Object_Destroy
+To record some traces :
+       lttng start
+       --> run your program
+       lttng stop
+To read some traces :
+       babeltrace ~/session_name
+To destroy your current tracing session :
+       lttng destroy
