>>104425573NTA but they are giving good advice, start without crazy nodes, since you already know the WebUI lingo you'll get settled in no time.
Start installing custom nodes as you need them, the three common ones I like are:
-efficiency-nodes-comfyui (LoRa Stacker and Ksampler)
-Comfyroll_CustomNodes (Apply stacker with model and clip, Upscale image)
-was-node-suite-comfyui (Very customizable image save node)
And if you want a base template with an upscaler just download this image and drop it into your UI, bare in mind, it will pop up a window telling you to install the nodes I mentioned above, in general be careful with that because there are people that upload malware, but you can trust me because I say so
