+### `stdsimd` examples
+
+This crate is a port of example uses of `stdsimd`, mostly taken from the `packed_simd` crate.
+
+The examples contain, as in the case of `dot_product.rs`, multiple ways of solving the problem, in order to show idiomatic uses of SIMD and iteration of performance designs.
+
+Run the tests with the command 
+
+```
+cargo run --example dot_product
+```
+
+and verify the code for `dot_product.rs` on your machine.
