A good tutorial/training or whatever about Replacement Shaders?

Blob

Hello,

I'm in need of the replacement shader to create custom effects for my game, but I don't have a clue how it works, even with the provided Replacement shaders exemple, and I didn't found any good tutorial via Google.

Do anyone know of a good tutorial, course or training, demonstrating step by step how to use replacement shaders?
