-# Install SciPy
-    $ /path/to/blender/2.xx/python/bin/python3.7m -m pip install -U scipy
-The following nodes become available only when you install SciPy:
-* Intersect Curve with Plane
-* RBF Curve
-* Nearest Point on Curve
-* Catenary Curve
-* Interpolate Curve Frame
-* Approximate Bezier Curve
-* Ortho Project on Curve
-* Curve Extremes
-* Minimal Scalar Field
-* Minimal Vector Field
-* Minimal Surface
-* Minimal Surface from Curve
-* Intersect Curve with Surface
-* Surface Raycast
-* Nearest Point on Surface
-* Ortho Project on Surface
-* Surface Extremes
-* Implicit Surface Raycast
-* Voronoi 3D
-* Delaunay 3D
-* Voronoi on Sphere
-The following nodes can optionally use SciPy:
-* Mesh Normal Field
-* Interpolating Surface
-# Install SciKit-Image
-    $ /path/to/blender/2.xx/python/bin/python3.7m -m pip install -U scikit-image
-The following nodes become available only when you install SciKit-Image:
-* Marching Squares
-* Marching Squares on Surface
-* Scalar Field Graph
-The following node can optionally use SciKit-Image:
-* Marching Cubes
-# Install Circlify
-    $ /path/to/blender/2.xx/python/bin/python3.7m -m pip install -U circlify
-The following node becomes available only when you install Circlify:
-* Circlify
-# Install PyMCubes
-This is more complex. First, you have to install [Cython][7]:
-    $ /path/to/blender/2.xx/python/bin/python3 -m pip install Cython
-Then you have to set up a build environment for Cython. You will need 1) to
-install development files for Python (such as `Python.h` and others), and 2) to
-explain Blender's python where to find them. **Note**: you have to have headers
-for exactly the same version of Python that your Blender build is using.
-On Debian/Ubuntu, you can install Python's development files by `apt-get
-install libpython3.7-dev` for `python3.7m` used in Blender 2.80/2.81. On other
-Linux distros, the command will be similar. On Windows or MacOS this can be
-more tricky, I did not try.
-You have to somehow tell Blender's built-in python where to look for headers.
-I've found the simplest way is to do
-    $ ln -s /usr/include/python3.7m/* /path/to/blender/2.xx/python/include/python3.7m/
-There may be more correct way, but I do not know it.
-After that, you can install PyMCubes by
-    $ /path/to/blender/2.xx/python/bin/python3.7m -m pip install -U PyMCubes
-The following node can optionally use PyMCubes:
-* Marching Cubes
-# Install Geomdl
-In the simplest case, you can install Geomdl by
-    $ /path/to/blender/2.xx/python/bin/python3.7m -m pip install -U geomdl
-but this way you will get pure-python library, which is very slow. If you want
-it fast, then you have to install Cython (see previous paragraph for
-instruction). After you installed Cython, you can install "cythonized" geomdl
-as it is described in [Geomdl instruction][9]:
-    $ /path/to/blender/2.xx/python/bin/python3 -m pip install geomdl --install-option="--use-cython"
-### Windows
-To get geomdl to compile
-After you install Cython via pip...
-Install the same version of Python that your install of Blender uses from [python.org][18]
-* Blender 2.9 == [Python 3.7][19]
-This will give you the /includes and /libs. Make sure on the Advanced screen of the installer you choose 'Precompile standard library' and 
-'Download debugging symbols'
-After install is complete, open up a Command Prompt (not Powershell). You will be making symbolic links from the /libs and /include from the python installation.
-* For the ```/libs``` directory
-```
-mklink /D "C:\Program Files\Blender Foundation\Blender 2.90\2.90\python\libs" "C:\Users\<username>\AppData\Local\Programs\Python\Python37\libs"
-```
-* For the ```/include``` directory
-```
-mklink /D "C:\Program Files\Blender Foundation\Blender 2.90\2.90\python\include" "C:\Users\<USERNAME>\AppData\Local\Programs\Python\Python37\include"
-```
-You should now be able to install geomdl with ```--use-cython``` arguments
-The following nodes become available only when you install Geomdl:
-* Approximate NURBS Curve
-* Approximate NURBS Surface
-* Interpolate NURBS Surface
-* Quads to NURBS
-* NURBS to JSON
-* JSON to NURBS
-The following nodes can optionally use Geomdl:
-* Build NURBS Curve
-* Build NURBS Surface
-* Interpolating Surface
-* Interpolate NURBS Curve
-* NURBS In
-# Install FreeCAD py3lib 
-You have to use FreeCAD of version 0.18 (0.19 could not work).
-### Linux:  
-1. Install FreeCAD (or just it's libraries, that will be enough):
-    $ sudo apt install libfreecad-python3-0.18    
-Note that in Ubuntu there is a [bug](https://bugs.launchpad.net/ubuntu/+source/freecad/+bug/1866914) in FreeCAD package; so if you are having error messages like `libnglib.so: no such file or directory`, then to work around this bug, you have to do the following:
-    $ sudo apt install libnglib-6.2.1804    
-    $ sudo echo '/usr/lib/x86_64-linux-gnu/netgen' >> /etc/ld.so.conf.d/x86_64-linux-gnu.conf  
-    $ sudo ldconfig  
-2. In Sverchok preferences dialog, in the "FreeCAD python path" field, enter `/usr/lib/freecad-python3/lib/` and press the "Set Path" button.
-3. Restart Blender.
-### Windows: 
-Download and install [FreeCAD for Windows][17]
-Add sverchok freecad-python3-lib path:  
-    ...\conda-0.18.3\bin  
-### MacOS
-The current version of FreeCAD has a different version of Python (3.8) so you must use ```conda-forge``` to retrieve a version compiled against Python 3.7.
-Follow the [recipe at FreeCAD Web][20]
-While it is ```activated``` type ```which freecad``` and use this path for the sverchok FreeCad lib path in Preferences. Don't forget to press 'Set Path' before closing the dialog. Restart Blender to take effect.
