+    """LIBXSMM is high performance library for small dense and sparse linear
+    algebra opertions incl. GEMM and elementwise primities often seen in deep
+    learning applications. It also serves as reference implementation of Tensor
+    Processing Primitives (TPP), a programming abstraction for efficient and
+    portable deep learning and HPC workloads. With version 2.0, LIBXSMM focuses
+    on providing a complete and architecture-portable set of TPPs (small dense
+    and sparse matrix operations as well as element-wise, GEMM, and BRGEMM
+    primitives) from which higher-level operators such as convolutions,
+    fully-connected layers, normalization, and pooling are composed. LIBXSMM
+    targets Intel Architecture with Intel SSE, Intel AVX, Intel AVX2, Intel
+    AVX‑512 (with VNNI and Bfloat16), and Intel AMX (Advanced Matrix
+    Extensions), AArch64 (NEON, SVE, and SME), and RISC‑V (RVV). Code generation
+    is mainly based on Just‑In‑Time (JIT) code specialization for
+    compiler-independent performance (matrix multiplications, matrix
+    transpose/copy, sparse functionality, and tensor primitives). LIBXSMM is
+    suitable for "build once and deploy everywhere", i.e., no special target
+    flags are needed to exploit the available performance. Supported GEMM
+    datatypes are: FP64, FP32, FP16, bfloat16, BF8, HF8, MXBF8, MXHF8, int16,
+    int8, MXBF6, MXHF6, MXFP4, int4, int2 and int1. Additionally, various
+    non-standard low precision combinations are supported."""
