+## Developing
+
+The specification is generated using the [Rust] packages contained with `packages` directory. In particular, [`utoipa`] is used to autogenerate the OpenAPI 3.0 specification. An [Actix Web] server is provided that (a) provides the foundation for `utoipa` to generate the API documentation and (b) provides an example server using fake data. Please refer to the [Learn Rust] guide to learn how to develop using Rust.
