+//! # `litemap`
+//!
+//! `litemap` is a crate providing [`LiteMap`], a highly simplistic "flat" key-value map
+//! based off of a single sorted vector.
+//!
+//! The goal of this crate is to provide a map that is good enough for small
+//! sizes, and does not carry the binary size impact of [`HashMap`](std::collections::HashMap)
+//! or [`BTreeMap`](alloc::collections::BTreeMap).
+//!
+//! If binary size is not a concern, [`std::collections::BTreeMap`] may be a better choice
+//! for your use case. It behaves very similarly to [`LiteMap`] for less than 12 elements,
+//! and upgrades itself gracefully for larger inputs.
+//!
+//! ## Pluggable Backends
+//!
+//! By default, [`LiteMap`] is backed by a [`Vec`]; however, it can be backed by any appropriate
+//! random-access data store, giving that data store a map-like interface. See the [`store`]
+//! module for more details.
+//!
+//! [`Vec`]: alloc::vec::Vec
