So what is it?

This is Bilibili's AI lab repository on GitHub. Bilibili is a Chinese video platform, and this repo appears to be where the company publishes AI research and tools. The README is very sparse and contains almost no description of the repository's overall scope or purpose. The one project mentioned in the README is Real-CUGAN, described as "Real Cascade U-Nets for Anime Image Super Resolution." This is a tool for increasing the resolution of anime-style images using a type of neural network. The details for that project are kept in a subdirectory of the same repository rather than in the top-level README. No other projects or tools are described in the available README text.

Copy-paste prompts

Prompt 1
I have the bilibili/ailab repo with Real-CUGAN. How do I run it on a folder of anime images to upscale them to 2x resolution?
Prompt 2
