+Rust-Lightning is a Bitcoin Lightning library written in Rust. The main crate,
+`lightning`, does not handle networking, persistence, or any other I/O. Thus,
+it is runtime-agnostic, but users must implement basic networking logic, chain
+interactions, and disk storage.
+
+The `lightning-net-tokio` crate implements Lightning networking using the
+[Tokio](https://github.com/tokio-rs/tokio) async runtime.
