 //! `FixedBitSet` is a simple fixed size set of bits.
 //!
-//!
 //! ### Crate features
 //!
 //! - `std` (default feature)  
 //!   Disabling this feature disables using std and instead uses crate alloc.
-//!   Requires Rust 1.36 to disable.
 //!
-//! ### Rust Version
+//! ### SIMD Acceleration
+//! `fixedbitset` is written with SIMD in mind. The backing store and set operations will use aligned SIMD data types and instructions when compiling
+//! for compatible target platforms. The use of SIMD generally enables better performance in many set and batch operations (i.e. intersection/union/inserting a range).
 //!
-//! This version of fixedbitset requires Rust 1.39 or later.
+//!  When SIMD is not available on the target, the crate will gracefully fallback to a default implementation.  It is intended to add support for other SIMD architectures
+//! once they appear in stable Rust.
 //!
-#![doc(html_root_url = "https://docs.rs/fixedbitset/0.4.2/")]
+//! Currently only SSE2/AVX2 on x86/x86_64 and wasm32 SIMD are supported as this is what stable Rust supports.
