-A tus resumable upload client for Rust (WIP)
+A [tus](https://tus.io) **resumable upload client** for Rust.
+
+> **Work in progress.** The API is not stable yet.
+
+## What is tus?
+
+[tus](https://tus.io/protocols/resumable-upload) is an open protocol for resumable file uploads over HTTP. Uploads can be interrupted and resumed without re-uploading data, making it ideal for large files and unreliable networks.
+
+## Features

+| Expiration handling            | 🚧 Partial (parsed, not acted on) |
