+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and

-//! # Case
+//! # UniCase
 //!
-//! Case provices a way of specifying strings that are case-insensitive.
+//! UniCase provices a way of specifying strings that are case-insensitive.
+//!
+//! UniCase supports full [Unicode case
+//! folding](https://www.w3.org/International/wiki/Case_folding). It can also
+//! utilize faster ASCII case comparisons, if both strings are ASCII.
+//!
+//! Using the `UniCase::new()` constructor will check the string to see if it
+//! is all ASCII. When a `UniCase` is compared against another, if both are
+//! ASCII, it will use the faster comparison.
+//!
+//! There also exists the `Ascii` type in this crate, which will always assume
+//! to use the ASCII case comparisons, if the encoding is already known.
 //!
 //! ## Example
 //!
 //! ```rust
 //! use unicase::UniCase;
 //!
-//! let a = UniCase("foobar");
-//! let b = UniCase("FoObAr");
+//! let a = UniCase::new("Maße");
+//! let b = UniCase::new("MASSE");
+//! let c = UniCase::new("mase");
+//!
+//! assert_eq!(a, b);
+//! assert!(b != c);
+//! ```
+//!
+//! ## Ascii
+//!
+//! ```rust
+//! use unicase::Ascii;
+//!
+//! let a = Ascii::new("foobar");
+//! let b = Ascii::new("FoObAr");
 //!
 //! assert_eq!(a, b);
 //! ```
