+# CUTLASS 3.0
+
+_CUTLASS 3.0 - January 2023_
+
+CUTLASS is a collection of CUDA C++ template abstractions for implementing
+high-performance matrix-multiplication (GEMM) at all levels and scales within CUDA.
+It incorporates strategies for hierarchical decomposition and data movement similar
+to those used to implement cuBLAS.  CUTLASS decomposes these "moving parts" into
+reusable, modular software components abstracted by C++ template classes.  These
+components can be specialized
+and tuned via custom tiling sizes, data types, and other algorithmic policies. The
+resulting flexibility simplifies their use as building blocks within custom kernels
+and applications.
+
+To support a wide variety of applications, CUTLASS provides extensive support for
+mixed-precision computations, providing specialized data-movement and
+multiply-accumulate abstractions for 8-bit integer, half-precision floating
+point (FP16), single-precision floating point (FP32), and double-precision floating
+point (FP64) types.  Furthermore, CUTLASS exploits the _Tensor Cores_ and asynchronous
+memory copy operations of the latest NVIDIA GPU architectures.
+
+# What's New in CUTLASS 3.0
+
+For an overview of CUTLASS 3.0's GEMM interface levels,
+please refer to the
+[CUTLASS 3.0 GEMM API document](./gemm_api_3x.md).
+To learn how to migrate code using CUTLASS 2.x's interface
+to CUTLASS 3.0, please refer to the
+[backwards compatibility document](./cutlass_3x_backwards_compatibility.md).
+
+# GEMM examples
+
+For a code example showing how to define
+a GEMM kernel using CUTLASS, please refer to
+[the quickstart guide](./quickstart.md).
+The [`examples` directory](https://github.com/NVIDIA/cutlass/tree/main/examples)
+has a variety of examples.
