Hi, I'm Niels, part of the community science team at Hugging Face. This PR aims to improve the model card for HDTree by:
- Adding the `unconditional-image-generation` pipeline tag to the metadata for better discoverability.
- Adding a link to the research paper: [HDTree: Generative Modeling of Cellular Hierarchies for Robust Lineage Inference](https://huggingface.co/papers/2506.23287).
- Including sample usage instructions for validating the checkpoints based on the official GitHub repository.
- Linking the project page and source code for better accessibility.
