+## 📖 Work in Progress: Geospatial Modeling with Python
+
+We are writing an open, freely accessible book on geographic data science and discrete spatial simulation with Python.
+
+The book covers three parts: Python for Data Science, Geographic Data Science with Python, and Discrete Spatial Modeling — including the DisSModel framework and real-world coastal dynamics case studies.
+
+Content is being developed gradually and released chapter by chapter. Feedback and contributions are welcome.
