Wire It in ComfyUI

You opened ComfyUI once. You saw a canvas full of boxes and wires, got an image you did not ask for, and closed the window. This book gets you back in and keeps you there. A node graph looks intimidating because it shows everything, and that is exactly why it is worth learning: every image is the output of a chain you can read, change one step at a time, save, and run again later exactly as you left it. You will install ComfyUI the current way, read the default workflow node by node, and learn what actually travels along each wire. You will learn what the sampler's controls do and how to compare them honestly, where models belong and which files to trust, how to add a style with a LoRA, rework an existing image, repair part of one with a mask, guide composition with ControlNet, and upscale a draft into a finished piece. You will learn to install custom nodes without breaking your setup or trusting the wrong code, and to build workflows clean enough to hand to someone else. No hype and no hardware worship. Just a graph you understand, one node at a time.
