langgptai/LangGPT ? reverse-engineered prompt

Build me a clean, easy to use website and companion repo for LangGPT, the prompt writing framework that helps people make structured, reusable prompts for AI. I want the site to explain the idea in simple language, show the basic prompt template, and give clear examples people can copy and adapt for different use cases like writing, planning, assistants, and custom roles.

Please include a quick start page, a examples gallery, and a section with the core rules and workflow for writing prompts the LangGPT way. It should also support the existing English, Chinese, and Japanese content, and make it easy to browse the theory notes and guides without feeling overwhelming. If anything is unclear, look up the current docs online and follow the style of the project. The result should feel polished, friendly, and practical, like a hub that helps anyone become better at prompting fast.
