+*kvSIMD.swift* is a cross-platform vectorization-friendly implementation of the SIMD framework interface on Swift.
 
-Preferred way to import *kvSIMD.swift* is `import kvSIMD`.
-*kvSIMD* module is the same as `import simd` or `import kvSimdImpl` whether the SIMD framework is available.
-Use `import kvSimdImpl` to import custom implementation unconditionally.
+Structure of package is designed to import *kvSIMD.swift* via `import simd` expression when the SIMD framework is unavailable.
+So `import simd` expression imports the SIMD framework if available and *kvSIMD.swift* otherwise.
 
 There are no explicit restrictions for any platform.
 So it's assumed that *kvSIMD.swift* is compiled on any platform Swift is available on.
 It's checked on macOS and Linux (Ubuntu 22.04).

 *kvSIMD.swift* is covered by unit-tests.
