+# 🌍 Tiny Multilingual CAPTCHA Library
+
+**Repository:** `remiai3/tiny-captcha-library`  
+
+A multilingual dataset of **synthetic 4-character CAPTCHA images** designed for **OCR, multilingual vision models, and script recognition research**.
+
+This dataset spans **23 world writing systems** and is especially useful for **low-resource script OCR training**.
+
+---
+
+## 📌 Dataset Summary
+
+Each script includes **10,000 unique CAPTCHA images**.  
+The dataset is provided in **two parallel formats**:
+
+- **CSV version** (standard ML workflows)
+- **Parquet version** (faster loading for large-scale pipelines)
+
+⚠️ The images inside both folders are **identical** — only the label file format differs.
+
+So per language:
+- 10,000 unique images  
+- 10,000 duplicate copies (same images, different label format)  
+

+## 🎯 Intended Use
+
+This dataset is designed for:
+
+- Multilingual OCR training  
+- Vision-language model pretraining  
+- Script recognition research  
+- Robust text recognition under distortion  
+
+🚫 Not intended for bypassing real-world CAPTCHA security systems.
