 - ✅ 支持自定义域名
 - ✅ 自动部署（Git 推送后自动更新）
 
+**✨ 数据库模式**：
+- 默认自动使用**本地数据库模式**（IndexedDB），数据存储在浏览器中
+- 无需配置任何数据库，开箱即用
+- 如需使用 Supabase 云端数据库，可在环境变量中配置
+
 **⚠️ 注意事项**：
 - Vercel 主要用于前端部署，后端 API 需单独部署
-- 推荐使用本地数据库模式（`VITE_USE_LOCAL_DB=true`）
 - 部署后可在 `/admin` 页面进行运行时配置

+**✨ Database Mode**:
+- Automatically uses **local database mode** (IndexedDB) by default, data stored in browser
+- No database configuration needed, ready to use out of the box
+- To use Supabase cloud database, configure environment variables
+
 **⚠️ Important Notes**:
 - Vercel is primarily for frontend deployment; backend APIs need separate deployment
-- Recommended to use local database mode (`VITE_USE_LOCAL_DB=true`)
 - After deployment, configure runtime settings at `/admin` page
