+[Godot Rapier][godot_rapier_github] written by [@Ughuuu](https://github.com/Ughuuu)
+is a physics plugin for [Godot][godot] that uses [Rapier][rapier], a popular
+physics engine written in Rust.
+
+Godot Rapier was originally written in C++, 
+and is now in the final stage of being completely rewritten in Rust.
+
+Its author wrote [an article on Reddit][godot_rapier_reddit] 
+about their experience with the rewrite. 
+Note that in the meantime the web exports have been fixed.
+
+Godot Rapier's website was adopted as a Rapier subdomain at
+[https://godot.rapier.rs/](https://godot.rapier.rs/).
+There you can also find a [progress overview](https://godot.rapier.rs/docs/progress).
