+//! To encode a string, do the following:
+//!
+//! ```rust
+//! use urlencoding::encode;
+//!
+//! let encoded = encode("This string will be URL encoded.");
+//! println!("{}", encoded);
+//! // This%20string%20will%20be%20URL%20encoded.
+//! ```
+//!
+//! To decode a string, it's only slightly different:
+//!
+//! ```rust
+//! use urlencoding::decode;
+//!
+//! let decoded = decode("%F0%9F%91%BE%20Exterminate%21").expect("UTF-8");
+//! println!("{}", decoded);
+//! // 👾 Exterminate!
+//! ```
+//!
+//! To decode allowing arbitrary bytes and invalid UTF-8:
+//!
+//! ```rust
+//! use urlencoding::decode_binary;
+//!
+//! let binary = decode_binary(b"%F1%F2%F3%C0%C1%C2");
+//! let decoded = String::from_utf8_lossy(&binary);
+//! ```
+//!
+//! This library returns [`Cow`](https://doc.rust-lang.org/stable/std/borrow/enum.Cow.html) to avoid allocating when decoding/encoding is not needed. Call `.into_owned()` on the `Cow` to get a `Vec` or `String`.
