 ## Blender-python version
+Navipy can be interfaced with blender. It is highly recommended to use the same version of packages of blender when doing so, in order to reduce problem of compatibility.
+To determine the packages that you will need, you can run the script: `navipy/script/check_blender_versions_pip.py` in blender or via commandline:
+
+```
+blender -b -P check_blender_versions_pip.py
+```
+
+It will create a textfile containing all packages used by blender. They can be installed in your virtualenvironment (prior to navipy) by doing:
+```
+pip install -r requirement.txt
+```
+
