+### [Rapier: 2D and 3D Physics Engines Focused on Performance][rapier-august]
+
+[![Rapier logo](rapier-logo.svg)][Rapier]
+
+[Rapier] is a new set of 2D and 3D physics engines written 100% in Rust.
+It is 5 to 10 times faster than [nphysics], close to the performances of the
+CPU version of PhysX, and often slightly faster than Box2D.
+
+[For its first release][rapier-august] Rapier includes:
+
+- rigid-body dynamics;
+- colliders and sensors;
+- joint constraints;
+- optional serialization of the physics state;
+- optional cross-platform determinism on IEEE-754 compliant targets;
+- optional explicit SIMD and parallelism.
+- JavaScript bindings with official NPM packages.
+
+This new physics engine is developed by the recently created [Dimforge]
+single-member Open-Source company [replacing][dimforge-replace] the former
+Rustsim organization created on GitHub by [@sebcrozet].
