-`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. More information is available in the `About`

 Status
 ------
-The project implements all of the [BOLT
-specifications](https://github.com/lightning/bolts). The
-implementation has pretty good test coverage that is expected to continue to
-improve. It is also anticipated that as developers begin using the API, the
-lessons from that will result in changes to the API, so any developer using this
-API at this stage should be prepared to embrace that. The current state is
-sufficient for a developer or project to experiment with it.
+The project implements all of the [BOLT specifications](https://github.com/lightning/bolts),
+and has been in production use since early 2022.
