 # Getting Started
 
+## Why Python?
+
+Python has become the standard language for data science and geographic analysis,
+with a rich ecosystem of libraries that complement each other naturally:
+
+- **Greater flexibility** — NumPy, SciPy, Pandas, GeoPandas, rasterio, and
+  machine learning frameworks can all be integrated into the same workflow,
+  allowing models of arbitrary complexity.
+- **Active development** — the Python geospatial community is extremely active,
+  with frequent updates, extensive documentation, and strong support for
+  reproducible research practices.
+- **Accessibility** — Python is widely considered one of the easiest languages
+  to learn, making spatial modeling more approachable for environmental scientists
+  and territorial planners who are not primarily software developers.
+
+DisSModel builds on this ecosystem rather than replacing it. A DisSModel simulation
+is just Python — the full power of the scientific stack is available at every step.
+
 ## Installation
