+# 🔍 ArchXAI Estonian OCR Dataset
+
+## Dataset Description
+
+This dataset contains 3,255 annotated text regions from Estonian historical documents, designed for optical character recognition (OCR) and document analysis tasks. The dataset includes images of text regions along with their corresponding transcriptions, and source documents.
+
+## 📊 Dataset Summary
+
+- **Total Examples**: 3,255
+- **Language**: 🇪🇪 Estonian
+- **Dataset Size**: ~758 MB
+- **Task**: OCR, Text Detection, Document Analysis
+- **Domain**: Historical Documents, Archival Materials
+
+## 🗂️ Dataset Structure

+
+## 💻 Usage Examples
+
+```python
+from datasets import load_dataset
+
+# Load the dataset
+dataset = load_dataset("Rahvusarhiiv/ArchXAI_Estonian")
+
+# Access a sample
+sample = dataset['train'][0]
+image = sample['image']
+text = sample['text']
+
+# Filter by document
+ordered_text = dataset['train'].sort('document')
+```
+
+## 🎯 Use Cases
+
+This dataset is valuable for:
+
