+## Python Binding
+
+You can create a RPR Python binding extension.
+
+Build the RPR binding libraries:
+```
+> cd python/
+> mkdir build
+> cd build
+> cmake -Dnanobind_DIR=nanobind/cmake ..
+> cmake --build . --config Release
+```
+Those builds will be generated inside python/build/Release/ they are needed by the python script running RPR in order to execute the:
+```
+import rpr
+import rprs
+import rprgltf
+```
+
+Run some test scripts:
+```
+> cd python/test
+> python test_script_rpr.py
+> python test_script_gltf.py
+```
+If tests run correctly, you should find the generated rendering images inside the python/test folder.
