+== Welcome!
+
+Welcome to the **LTTng Documentation**!
+
+The _Linux Trace Toolkit: next generation_ is an open source software
+toolkit which you can use to simultaneously trace the Linux kernel, user
+applications, and user libraries.
+
+LTTng consists of:
+
+* Kernel modules to trace the Linux kernel.
+* Shared libraries to trace user applications written in C or C++.
+* Java packages to trace Java applications which use
+ `java.util.logging`.
+* A kernel module to trace shell scripts and other user applications
+ without a dedicated instrumentation mechanism.
+* Daemons and a command-line tool, cmd:lttng, to control the
+ LTTng tracers.
