+stdarch - Rust's standard library SIMD components
+=======
+
+[![Actions Status](https://github.com/rust-lang/stdarch/workflows/CI/badge.svg)](https://github.com/rust-lang/stdarch/actions)
+
+
+# Crates
+
+This repository contains two main crates:
+
+* [`core_arch`](crates/core_arch/README.md) implements `core::arch` - Rust's
+ core library architecture-specific intrinsics, and
+
+* [`std_detect`](crates/std_detect/README.md) implements `std::detect` - Rust's
+ standard library run-time CPU feature detection.
+
+The `std::simd` component now lives in the
+[`packed_simd_2`](https://github.com/rust-lang/packed_simd) crate.
