ComfyUI on Runpod

Hi, I'm new to renting GPUs and ComfyUI. I have a basic laptop that can't run ComfyUI locally. I'd like to rent GPUs to start learning and earn later to get myself a PC. Anybody here can please guide me how to use ComfyUI on runpod? I also want to know do we get comfy manager in there? How to download models, nodes in there? Do I need to use wget, Aria2c? Please help me out. I'm a newbie with almost zero knowledge. Thanks in advance.
