- A "Getting Started" section guiding users to the comprehensive documentation on the GitHub repository for setup and dataset download.
- The appropriate `task_categories` (`robotics`) and relevant `tags` (`world-model`, `embodied-ai`, `benchmark`) to the metadata.
- The BibTeX citation for the paper.
