Since I posted the last update on Reddit, the official Factorio Forums get word of today's update. Please enjoy!

This guide is a work in progress! I only have 3 sections written up (backpressure introduction, red and green wires, and remote backpressure), that covers only red/green wires and constant combinators. Still, I have an ambitious outline and video-editing + text style that I hope you all can enjoy.
I'll be adding more sections as time goes on. My original outline was discussed on reddit, although I'm going to cut it short due to length. This project is taking far more video editing and writing than I expected.
The next section planned is "Pulse Mode Backpressure", which will introduce arithmetic and decider combinators.
