 Profiling with Caliper
 ************************
 
+To aid in profiling the RAJA abstraction layer has plug in support with the Caliper
+performance library. Caliper is developed at LLNL and freely available on GitHub `Caliper GitHub <https://github.com/LLNL/Caliper>`_ .
+Caliper provides a common interface for various vendor profiling tools, its own built in performance reports.
 
+In this section we will demonstrate how to configure RAJA with Caliper, run simple examples with kernel performance,
+and finally use the Thicket library, also developed at LLNL and freely available on GitHub `Thicket GitHub <https://github.com/LLNL/Thicket>`_ .
+For more detailed tutorials we refer the reader to the Caliper and Thicket tutorials.
