 //! # Maplibre-rs
 //!
 //! A multi-platform library for rendering vector tile maps with WebGPU.
+//!
+//! Maplibre-rs is a map renderer that can run natively on MacOS, Linux, Windows, Android, iOS and the web.
+//! It takes advantage of Lyon to tessellate vector tiles and WebGPU to display them efficiently.
+//! Maplibre-rs also has an headless mode (*work in progress*) that can generate rasters.
+//!
+//! The official guide book can be found here #![doc = include_str!("description.md")]

+//! ### Example
+//!
+//! To import maplibre-rs in your `Cargo.toml`:
