## Where to find things

| Resource | Purpose |
|---|---|
| [jumper-design](https://github.com/KingKongRobotics/jumper-design) | Appearance and scene creation; your assistant reads its [instructions](https://github.com/KingKongRobotics/jumper-design/blob/main/AGENTS.md) and uses its tools as needed. |
| [Training tutorial](docs/TUTORIAL.md) | Motion training, replay and policy export in this repository. |
| [Colab training](docs/COLAB.md) | GPU training in a notebook, checkpoint backup, resume, ONNX export and MP4 simulation replay. |
| [Motion bundles](deploy/BUNDLE.md) | Package trained motions and their controller as an `.app`; see the [build guide](deploy/README.md) for prerequisites. |
| [Project guide](docs/PROJECT_GUIDE.md) | Setup, current capabilities and further documentation. |

Training builds on [mjlab](https://github.com/mujocolab/mjlab),
[rsl_rl](https://github.com/leggedrobotics/rsl_rl), [MuJoCo](https://github.com/google-deepmind/mujoco)
and [MuJoCo Warp](https://github.com/google-deepmind/mujoco_warp).
