I'm an ADC main, wanting to main Vayne. Where's the end all resource for learning advanced mechanics?

I've been an ADC main for 3 seasons now, and never really tried Vayne seriously. I'm starting to finally get to the point where I'm progressing through ranked very fast, and I'd love to start to main Vayne. I have her basic mechanics down fairly well, but I don't quite know what builds work best for her, and what are the more advanced mechanics of her are.

Anyone have any tips/tricks?
