-project. A brief summary is described below.

+[Doxygen documentation](https://nvidia.github.io/cutlass) provides a complete list of files, classes, 
+and template concepts defined in the CUTLASS project.
 
-The CUTLASS library is defined in the cutlass/ directory and consists of CUDA C++ template

-classes and templates define basic primitives that are then applied to compute GEMM via
-templates in the cutlass/gemm directory.

+[CUTLASS documentation](media/docs/code_organization.md), but several main components are summarized below.
