## Documentation

- [Introduction](/getting-started/introduction): Jolt physics in React — a react-three-fiber wrapper around the Jolt Physics engine.
- [Installation](/getting-started/installation): Install @react-three/jolt and its peers, and get the WASM module through your bundler.
- [Physics](/api/physics): The Physics world component, its props, and the systems behind it.
- [RigidBody](/api/rigid-body): The RigidBody component, its props, and the BodyState object you get from its ref.

- [Colliders](/api/colliders): Named collider components, the args convention, and controlling a body's automatic shape with colliders.
- [Queries](/api/queries): Raycasting, shapecasting and collide-shape overlap tests, and who owns what.
- [Collision groups & layers](/api/collision-groups): Group and sub-group filtering, and the object/broad-phase layers the library presets.
- [Controllers](/api/controllers): CharacterController, CameraRig and Vehicle from @react-three/jolt/controllers.
- [Addons](/api/addons): useCommand, useLookCommand and the commander — input mapped to named commands.
- [Memory & lifecycle](/advanced/memory): Who owns what in the WASM heap, and the rules that keep Jolt from corrupting itself.
- [SSR & Suspense](/advanced/ssr-and-suspense): How Physics suspends while the WASM module loads, and what to do when it fails.
