Node graphs look intimidating for about an hour. After that, they are the clearest way to build images that has ever existed - because every step is visible, and every step can be changed without redoing the rest. This handbook starts at installation and builds up one connection at a time, never assuming you know what a checkpoint, a sampler or a latent is. Every topic gets two pages: a plain-English explanation of what you are looking at and what to do, then a real screenshot with a short exercise. Forty-five topics, in build order. Inside: Install it, load your first model, and generate an image before anything gets complicated Read a node graph - what the boxes do, what the coloured lines carry, and why some connections are refused The settings that actually change your result: seed, steps, guidance and denoise Guide composition from a reference image, and keep a character's face consistent across shots Start from an existing picture: transform it, upscale it, mask part of it, or extend it beyond its borders Install extensions safely and recover workflows that arrive with missing nodes Fix the memory errors that stop most people, in the order worth trying
