-//! SIMD vectors
+//! SIMD vectors.
+//!
+//! These types can be used for accessing basic SIMD operations. Each of them
+//! implements the standard arithmetic operator traits (Add, Sub, Mul, Div,
+//! Rem, Shl, Shr) through compiler magic, rather than explicitly. Currently
+//! comparison operators are not implemented. To use SSE3+, you must enable
+//! the features, like `-C target-feature=sse3,sse4.1,sse4.2`, or a more
+//! specific `target-cpu`. No other SIMD intrinsics or high-level wrappers are
+//! provided beyond this module.
+//!
+//! ```rust
+//! #[allow(experimental)];
+//!
+//! fn main() {
+//!     use std::simd::f32x4;
+//!     let a = f32x4(40.0, 41.0, 42.0, 43.0);
+//!     let b = f32x4(1.0, 1.1, 3.4, 9.8);
+//!     println!("{}", a + b);
+//! }
+//! ```
+//!
+//! ## Stability Note

+//! These are all experimental. The inferface may change entirely, without
+//! warning.
