+Documentation is available [on docs.rs](https://docs.rs/powerfmt).
+
+## Minimum Rust version policy
+
+`powerfmt` is guaranteed to compile with the latest stable release of Rust in addition to the two
+prior minor releases. For example, if the latest stable Rust release is 1.70, then `powerfmt` is
+guaranteed to compile with Rust 1.68, 1.69, and 1.70.
+
+The minimum supported Rust version may be increased to one of the aforementioned versions if doing
+so provides the end user a benefit. However, the minimum supported Rust version may also be bumped
+to a version four minor releases prior to the most recent stable release if doing so improves code
+quality or maintainability.
+
+For interoperability with third-party crates, it is guaranteed that there exists a version of that
+crate that supports the minimum supported Rust version of `powerfmt`. This does not mean that the
+latest version of the third-party crate supports the minimum supported Rust version of `powerfmt`.
+
+## Contributing
+
+Contributions are always welcome! If you have an idea, it's best to float it by me before working on
+it to ensure no effort is wasted. If there's already an open issue for it, knock yourself out.
+
+If you have any questions, feel free to use [Discussions]. Don't hesitate to ask questions — that's
+what I'm here for!

+//! Definition of [`SmartDisplay`] and its related items.
+//!
+//! [`SmartDisplay`] is a trait that allows authors to provide additional information to both the
+//! formatter and other users. This information is provided in the form of a metadata type. The only
+//! required piece of metadata is the width of the value. This is _before_ it is passed to the
+//! formatter (i.e. it does not include any padding added by the formatter). Other information
+//! can be stored in a custom metadata type as needed. This information may be made available to
+//! downstream users, but it is not required.
+//!
+//! This module contains the [`SmartDisplay`] and associated items.
+//!
+//! # Example
+//!
+//! ```rust
+//! use std::fmt;
+//!
+//! use powerfmt::ext::FormatterExt as _;
+//! use powerfmt::smart_display::{self, FormatterOptions, Metadata, SmartDisplay};
+//!
+//! #[derive(Debug)]
+//! struct User {
+//! id: usize,
+//! }
+//!
+//! // If you try to use `UserMetadata` in the `SmartDisplay` implementation, you will get a
+//! // compiler error about a private type being used publicly. To avoid this, use this attribute to
+//! // declare a private metadata type. You shouldn't need to worry about how this works, but be
+//! // aware that any public fields or methods remain usable by downstream users.
+//! #[smart_display::private_metadata]
+//! struct UserMetadata {
+//! username: String,
+//! legal_name: String,
+//! }
+//!
+//! // This attribute can be applied to `SmartDisplay` implementations. It will generate an
+//! // implementation of `Display` that delegates to `SmartDisplay`, avoiding the need to write
+//! // boilerplate.
+//! #[smart_display::delegate]
+//! impl SmartDisplay for User {
+//! type Metadata = UserMetadata;
+//!
+//! fn metadata(&self, _: FormatterOptions) -> Metadata<'_, Self> {
+//! // This could be obtained from a database, for example.
+//! let legal_name = "John Doe".to_owned();
+//! let username = "jdoe".to_owned();
+//!
+//! // Note that this must be kept in sync with the implementation of `fmt_with_metadata`.
+//! let width = smart_display::padded_width_of!(username, " (", legal_name, ")",);
+//!
+//! Metadata::new(
+//! width,
+//! self,
+//! UserMetadata {
+//! username,
+//! legal_name,
+//! },
+//! )
+//! }
+//!
+//! // Use the now-generated metadata to format the value. Here we use the `pad_with_width`
+//! // method to use the alignment and desired width from the formatter.
+//! fn fmt_with_metadata(
+//! &self,
+//! f: &mut fmt::Formatter<'_>,
+//! metadata: Metadata<Self>,

+//! f.pad_with_width(
+//! metadata.unpadded_width(),
+//! format_args!("{} ({})", metadata.username, metadata.legal_name),
