ymcui/Chinese-LLaMA-Alpaca ? reverse-engineered prompt

Build me a GitHub repo for a Chinese LLaMA and Alpaca project that helps people download, merge, run, and fine tune the models locally on a normal PC.

I want it to support the usual LLaMA style workflow, including LoRA merging, basic pretraining and instruction tuning scripts, and simple inference examples that can run on CPU or GPU. It should also include a small web demo for chatting, plus example notebooks and sample data or prompts so someone can try it quickly. Please make the instructions beginner friendly, with clear setup steps, model download guidance, and notes for common issues like quantization, prompt format, and using the right model for chat versus text completion.

If possible, include examples for integrating with common tooling like transformers and a local inference setup. Look up current docs online if you need to, and make the README easy to follow for someone who just wants to get a Chinese model running on their machine.
