+# Flickr30k
+
+This repository hosts a copy of the widely used **Flickr30k** dataset,
+a benchmark for image captioning and image–text retrieval.
+
+Flickr30k contains images paired with multiple human-written English captions per image and is widely used in multimodal research.
+
+## Contents
+Commonly included files/fields (exact filenames may vary):
+
+- Images (or image references)
+- Captions (often 5 captions per image)
+- Optional split / id fields
+
+A typical record conceptually looks like:
+```json
+{
+  "image": "<image>",
+  "caption": ["...", "...", "...", "...", "..."]
+}
+```
+
+## Usage
+```python
+from datasets import load_dataset
+ds = load_dataset("nlphuji/flickr30k")
+```
+
+## Source
+This dataset is taken from the Hugging Face dataset repository:
+https://huggingface.co/datasets/nlphuji/flickr30k
+
+## License
+The Hugging Face dataset card does not clearly specify a single unified license (“unknown” is shown in some metadata).
+Because the images originate from Flickr, usage is typically subject to the relevant **Flickr Terms & Conditions** and any per-image licensing.
+Please review the dataset’s original homepage and usage terms before redistribution or commercial use.
