-This book is intended as a guide for how to use [Roadster](https://crates.io/crates/roadster), a web framework for the
-Rust programming language. Compared to low-level web frameworks such as [Axum](https://github.com/tokio-rs/axum) or
-[Actix](https://actix.rs/), which only provide the functionality to create an API, Roadster aims to provide all the
-other functionality needed to create a fully-featured backend or fullstack web app for a more "batteries included"
-experience. Roadster is designed to provide sensible defaults for all features while remaining highly configurable,
-customizable, and pluggable. This allows you to focus on creating your application instead of wiring up all of your
-dependencies, while still allowing you the flexibility to customize your dependencies if needed.
