Where to find things
| Resource | Purpose |
|---|---|
| jumper-design | Appearance and scene creation; your assistant reads its instructions and uses its tools as needed. |
| Training tutorial | Motion training, replay and policy export in this repository. |
| Motion bundles | Package trained motions and their controller as an .app; see the build guide for prerequisites. |
| Project guide | Setup, current capabilities and further documentation. |
Training builds on mjlab, rsl_rl, MuJoCo and MuJoCo Warp. Example appearance and scene images come from jumper-design; image sources and third-party notices record attribution.
