Installation

geonodes is a python package. To install it, copy the package folder geonodes in scripts/modules.

The Blender scripts folder is defined in Blender preferences, see: Blender File Paths settings.

Note that geonodes is a python module, not an Blender addon

After the install, the Blender scripts hierarchy should look like:

.../scripts/
       modules/
           geonodes/
               __init__.py
               core
               demos
               ...

To make the module available in your script, use import in your script:

from geonodes import *
