Help with Starnet++ in Siril

I saw a tutorial on Siril website regarding the Starnet++ integration within Siril. I have installed all the appropriate items as listed in the tutorial except PIL. What is PIL and how do I install it?

Thank you.

Hi,

PIL stands for Python Image Library I think. Not sure it gets shipped with recent Python, but you can install its fork Pillow
Assuming you’re using pip:
pip install Pillow

Documentation here just in case:
