+# Geoman
+
+The Geoman plugin provides an interactive drawing and editing interface for polygons, polylines, circles, and other geometric shapes on your Folium map. It's based on the [Leaflet-Geoman](https://github.com/geoman-io/leaflet-geoman/) library.
+
+## Advantages over Draw Plugin
+
+Geoman is a more recent and actively maintained alternative to the Draw plugin, offering several key advantages:
+
+- **Advanced Shape Features**: Supports drawing shapes with holes inside them, which is not available in the Draw plugin
+- **Enhanced Editing Capabilities**: Includes cutting, rotating, scaling, and snapping functionality for precise geometry editing
+- **Professional Add-ons**: Offers [paid extensions](https://geoman.io/docs/leaflet/getting-started/pro-version) with advanced functionality for complex GIS applications
+
+## Basic Usage
+
+```{code-cell} ipython3
+import folium
+from folium.plugins import GeoMan
+
+# Create a map
+m = folium.Map(location=[45.5236, -122.6750], zoom_start=13)
+
+# Add Geoman plugin
+GeoMan().add_to(m)
+
+m
+```
+
+## Customizing Controls
+
+You can customize which drawing controls are available and their position:
+
+```{code-cell} ipython3
+import folium
+from folium.plugins import GeoMan
+
+m = folium.Map(location=[45.5236, -122.6750], zoom_start=13)
+
+# Add Geoman with custom options
+GeoMan(
+    position='topright',
+    drawMarker=True,
+    drawCircleMarker=True,
+    drawPolyline=True,
+    drawRectangle=True,
+    drawPolygon=True,
+    drawCircle=True,
+    drawText=False,
+    editMode=True,
+    dragMode=True,
+    cutPolygon=True,
+    removalMode=True,
+    rotateMode=False
+).add_to(m)
+
+m
+```
