+### Special consideration for Windows Users:
+
+There may be a need for pre-compiled wheel files to be installed for several packages (GDAL, Fiona, Shapely, pyproj, and Rtree). Downloading GDAL first will avoid dependency errors. You will need to taylor these downloads for your specific python version and architecture (ie., Python 3.14 64-bit)
+```Powershell
+python -m pip install --index https://gisidx.github.io/gwi gdal fiona shapely pyproj rtree
+```
+Verify your installation:
+```Powershell
+python -c "import geopandas; import fiona; import shapely; import pyproj; import rtree; print('All dependencies installed!')"
+```
+Install GeoPandas after the wheels:
+```Powershell
+python -m pip install geopandas
+```
+**Rationale** This package uses GDAL and Fiona which arenon-python C/ C++ code libraries. Pip cannot automatically build GDALon Windows so it needs precompiled binary packages (wheels).
