Hello !

Well first of all thank you for all the efforts that obviously went into it, as it looks like it covers pretty much everything.
Depending on how useful the Node Editor turns out to be for my own uses I might end up making a simplified, linear PDF version out of these help pages for easy reading. I'll let you know if that happens.
Regarding maintenance : well, even the most appropriate solutions for the authoring of such pages (like the very popular ReadTheDocs Python generator) can quickly become a pain as soon as the technical aspects (building the pages) gets in the way. So yeah as said I feel like the most streamlined solution is just a good old PDF with a bunch of pictures generated from a text document - just like the UE Compendiums really :)

Anyways, time to learn some node stuff now.
