It may not be entirely correct compared to the official workflow and how it uses a special node for sigma/scheduler, but it works well and fast. This one automatically handles the resolution for you and produces ~2K sized images, all you have to worry about is changing the aspect ratio. You can experiment with samplers and schedulers and more or less steps, but I find 8 steps to be a good amount for quality.
