+
+### Dataset Summary
+
+A smaller subset of 10 easily classified classes from [Imagenet](https://huggingface.co/datasets/imagenet-1k#dataset-summary), and a little more French.
+This dataset was created by [Jeremy Howard](https://twitter.com/jeremyphoward), and this repository is only there to share his work on this platform. The repository owner takes no credit of any kind in the creation, curation or packaging of the dataset.
+
+### Supported Tasks and Leaderboards
+
+- `image-classification`: The dataset can be used to train a model for Image Classification.
+
+### Languages
+
+The class labels in the dataset are in English.
+
+## Dataset Structure
+
+### Data Instances
+
+A data point comprises an image URL and its classification label.
+
+```
+{
+  'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=320x320 at 0x19FA12186D8>,
+  'label': 'tench',
+}
+```
+
+### Data Fields
+
+- `image`: A `PIL.Image.Image` object containing the image.
+- `label`: the expected class label of the image.
+
+### Data Splits
