+ (description "Accelerate SHA256 computations in pure Go using AVX512 and
+AVX2 for Intel and ARM64 for ARM. On AVX512 it provides an up to 8x
+improvement (over 3 GB/s per core) in comparison to AVX2.
+
+This package is designed as a replacement for @command{crypto/sha256}. For
+Intel CPUs it has two flavors for AVX512 and AVX2 (AVX/SSE are also
+supported). For ARM CPUs with the Cryptography Extensions, advantage is taken
+of the SHA2 instructions resulting in a massive performance improvement.
+
+This package uses Golang assembly. The AVX512 version is based on the Intel's
+\"multi-buffer crypto library for IPSec\" whereas the other Intel
+implementations are described in \"Fast SHA-256 Implementations on Intel
+Architecture Processors\" by J. Guilford et al.")
