+//! This crate provides an Active Storage Server. It implements simple reductions on S3 objects
+//! containing numeric binary data.  By implementing these reductions in the storage system the
+//! volume of data that needs to be transferred to the end user is vastly reduced, leading to
+//! faster computations.
+//!
+//! The work is funded by the
+//! [ExCALIBUR project](https://www.metoffice.gov.uk/research/approach/collaboration/spf/excalibur)
+//! and is done in collaboration with the
+//! [University of Reading](http://www.reading.ac.uk/).
+//!
+//! This is a performant implementation of the Active Storage Server.
+//! The original Python functional prototype is available
+//! [here](https://github.com/stackhpc/s3-active-storage).
+//!
+//! The Active Storage Server is built on top of a number of open source components.
+//!
+//! * [Tokio](tokio), the most popular asynchronous Rust runtime.
+//! * [Axum](axum) web framework, built by the Tokio team. Axum performs well in [various](https://github.com/programatik29/rust-web-benchmarks/blob/master/result/hello-world.md) [benchmarks](https://web-frameworks-benchmark.netlify.app/result?l=rust)
+//!   and is built on top of various popular components, including the [hyper] HTTP library.
+//! * [Serde](serde) performs (de)serialisation of JSON request and response data.
+//! * [AWS SDK for S3](aws-sdk-s3) is used to interact with S3-compatible object stores.
+//! * [ndarray] provides [NumPy](https://numpy.orgq)-like n-dimensional arrays used in numerical
+//!   computation.
