+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is a frontend project for a configuration settings UI. The goal is to produce a single, self-contained HTML file with all JavaScript and CSS inlined. The application should be designed with a clean, modern UI and support both English and Chinese languages.
+
+## Tech Stack
+
+- **Package Manager:** pnpm
+- **Build Tool:** Vite.js
+- **Framework:** React.js
+- **Styling:** Tailwind CSS with shadcn-ui
+- **Languages:** TypeScript, English, Chinese
+
+## Key Commands
+
+- **Run development server:** `pnpm dev`
+- **Build for production:** `pnpm build` (This produces a single HTML file)
+- **Lint files:** `pnpm lint`
+- **Preview production build:** `pnpm preview`
+
+## Architecture & Development Notes
+
+- **Configuration:** The application's configuration structure is defined in `config.example.json`. This file should be used as a reference for mocking data, as no backend APIs will be implemented.
+- **Build Target:** The final build output must be a single HTML file. This is configured in `vite.config.ts` using `vite-plugin-singlefile`.
+- **Internationalization (i18n):** The project uses `i18next` to support both English and Chinese. Locale files are located in `src/locales/`. When adding or changing text, ensure it is properly added to the translation files.
+- **UI:** The UI is built with `shadcn-ui` components. Refer to existing components in `src/components/ui/` for styling conventions.
+- **API Client:** The project uses a custom `ApiClient` class for handling HTTP requests with baseUrl and API key authentication. The class is defined in `src/lib/api.ts` and provides methods for GET, POST, PUT, and DELETE requests.
