I'm going to kick our discussion off by talking about node postprocessing. So note in this lesson and the lessons going forward, I'm not going to go through and run all the code for you. I'm going to let you go ahead and piece the patterns together yourself. That being said, let's go ahead and jump right into it, I want to talk to you about node postprocessing. A note that all this stuff right here, I've set it up for you, so all the quote-unquote boilerplate has been set up for you, so that if you do want to play around with these postprocessors, I'll leave that right up to you.
