-A simple middleware for extracting JWT tokens from requests and making them available to your handlers.
+A Rust library providing JWT authentication middleware for Axum web applications. It supports both local and remote JWKS validation, handles token extraction and validation, and provides strongly-typed claims access in your request handlers. Built on top of jsonwebtoken, it offers a simple yet flexible API for securing your Axum routes with JWT authentication.
 
 See [examples](./examples/) for how to use.
