I have a bad memory. 

Too often, even though I know I’ve set up something in Geo Nodes before, I can't remember how I did it and I can’t find the node setup quickly, so I’m left scrubbing through multiple video tutorials (that are always zoomed-in on partial node-trees) and bad AI suggestions trying to find the setup.

What I needed is a fast, easy reference, where I can get the basic setup for the technique I need so that I can then customize it based on the project at hand.

That's what this is: not a course, not a how-to on creating effects, but a list of 'recipes' showing what combination of nodes you need to create a specific effect. They are all numbered and laid out so you can reference them quickly, understand how to adjust them to suit your needs, and see how they get combined to do more advanced effects in much larger node trees.

There are a lot of great courses and videos out there; I am not trying to reproduce any of those. This cookbook is just a fast guide to finding the setup you need with a lot of space to expand it as I find more that I need to remember.
