List of all nodes and they explanation?

Hey,
There's any source for nodes to see what exactly they do?
There's so many of them without description

I think the manuals (Resolve and Fusion) cover most of them. Any particular ones that there's no documentation for? The documentation can fool you in that it may mention some things in earlier introductions to a capability and then mention some others in more of a list of paragraphs. (Granted, the explanations aren't all super-detailed.)
