+The Crello dataset is a collection of raster graphic designs originally compiled for the study of vector graphic documents. It contains document meta-data such as canvas size and pre-rendered elements such as images or text boxes. The original templates were collected from [crello.com](https://crello.com) (now [create.vista.com](https://create.vista.com/)) and converted to a low-resolution format suitable for machine learning analysis. More recently, it has been used for research into decomposing raster graphic designs into layers, as presented in the LayerD paper.

+### Sample Usage (LayerD Data Preparation)
+
+The LayerD project, which uses this dataset for training its top-layer matting module, provides a script to prepare the Crello dataset. You can convert the Crello dataset for this purpose using the following command from the LayerD repository:
+
+```bash
+uv run python ./tools/generate_crello_matting.py --output-dir </path/to/dataset> --inpainting --save-layers
+```
+
+> [!NOTE]
+> This script downloads [the Crello dataset](https://huggingface.co/datasets/cyberagent/crello) (<20GB) from Hugging Face. Please ensure you have a stable internet connection and sufficient disk space for the first run.

 ### Supported Tasks and Leaderboards
 
-[CanvasVAE](https://arxiv.org/abs/2108.01249) studies unsupervised document generation.
+The Crello dataset supports unsupervised document generation (as studied by CanvasVAE) and layer decomposition / image segmentation (as studied by LayerD).

 `left` and `top` can be negative because elements can be bigger than the canvas size.
 `text_line` indicates the index of the text line.
 For example, the following indicates that `Be` is in the first line and the rest in the next line.
-The newline character `\n` if present is ignored in rendering.
