Ok…I have hit a roadblock. I am following the guidance here:

[https://slicer.readthedocs.io/en/latest/developer\_guide/modules/volumerendering.html#how-to-register-custom-volume-rendering-presets](https://slicer.readthedocs.io/en/latest/developer_guide/modules/volumerendering.html#how-to-register-custom-volume-rendering-presets)

I have a new file called MyPresets.mrml in my Slicer Scene Location directory along with a PNG thumbnail.

Now I come to this instruction…  
" Use the following code to read all the custom presets from _MyPresets.mrml_ and load it into the scene:"

I do not know how to ‘use’ the code. I pasted it in the Python interpreter window. That did not work. I am betting I have to add to some file…but I do not know which one.
