 # blender-mapping-tools
 
-Blender extension for creating maps
-
-## Building
-
-TODO: make a proper build system.
-
-For Blender 4.4:
-
-```sh
-pip download rasterio --dest ./wheels --only-binary==:all: --python-version=3.11
-# Or replcace ".." below with any directory.
-# blender_mapping_tools-0.1.0.zip will be placed in that directory.
-blender --command extension build --output-dir ..
-```
-
-Then install `blender_mapping_tools-0.1.0.zip` as an extension in blender. It
-will add a "Mesh from GeoTIFF" option to the "Add" menu.
