+# 🌍 Geographic Coordinate Extractor
+---
+This Space demonstrates the performance of AI models trained to automate the extraction of geographical coordinates from the 18th-century **Encyclopédie of Diderot and d'Alembert**.
+
+### 🛠️ How it Works:
+1. **Classification:** A BERT-like model identifies whether a given encyclopedia entry contains geographic coordinates.
+2. **Extraction & Normalization:** An mT5-based model retrieves raw coordinate strings from the text and normalizes them into a standard DMS format.
+
+You can test the models by entering a custom text or choosing from the examples provided.
