 ## What you can manage (mapped to the UI pages)
 
 - **Dashboard**: connection status, server version/build date, quick counts, model availability snapshot.
-- **Basic Settings**: debug, proxy URL, request retry, quota fallback (switch project/preview models), usage statistics, request logging, file logging, WebSocket auth.
+- **Basic Settings**: debug, proxy URL, request retry, quota fallback (switch project or preview models when limits reached), usage statistics, request logging, file logging, WebSocket auth.
 - **API Keys**: manage proxy `api-keys` (add/edit/delete).
 - **AI Providers**:
-  - Gemini/Codex/Claude key entries (base URL, headers, proxy, model aliases, excluded models, prefix).
-  - OpenAI-compatible providers (multiple API keys, custom headers, model alias import via `/v1/models`, optional browser-side “chat/completions” test).

+- **Auth Files**: upload/download/delete JSON credentials, filter/search/pagination, runtime-only indicators, view supported models per credential (when the server supports it), manage OAuth excluded models (supports `*` wildcards), configure OAuth model alias mappings.
 - **OAuth**: start OAuth/device flows for supported providers, poll status, optionally submit callback `redirect_url`; includes iFlow cookie import.
+- **Quota Management**: manage quota limits and usage for Claude, Antigravity, Codex, Gemini CLI, and other providers.
 - **Usage**: requests/tokens charts (hour/day), per-API & per-model breakdown, cached/reasoning token breakdown, RPM/TPM window, optional cost estimation with locally-saved model pricing.
 - **Config**: edit `/config.yaml` in-browser with YAML highlighting + search, then save/reload.
 - **Logs**: tail logs with incremental polling, auto-refresh, search, hide management traffic, clear logs; download request error log files.
 - **System**: quick links + fetch `/v1/models` (grouped view). Requires at least one proxy API key to query models.
 
+## Tech Stack
+
+- React 19 + TypeScript 5.9
+- Vite 7 (single-file build)
+- Zustand (state management)
+- Axios (HTTP client)
+- react-router-dom v7 (HashRouter)
+- Chart.js (data visualization)
+- CodeMirror 6 (YAML editor)

+## Internationalization
+
+Currently supports three languages:
+
+- English (en)
+- Simplified Chinese (zh-CN)
+- Russian (ru)
+
+The UI language is automatically detected from browser settings and can be manually switched at the bottom of the page.
+
+## Browser Compatibility
+
+- Build target: `ES2015`
+- Supports modern browsers (Chrome, Firefox, Safari, Edge)
+- Responsive layout for mobile and tablet access

 ## Build & release notes
 
 - Vite produces a **single HTML** output (`dist/index.html`) with all assets inlined (via `vite-plugin-singlefile`).
