+```
+
+## 初始化資料庫
+
+1. 安裝依賴：
+```bash
+pnpm install
+```
+
+2. 初始化資料庫：
+```bash
+pnpm run db:init
+```
+
+3. 測試資料庫連接：
+```bash
+pnpm run db:test
+```
+
+## 資料表結構
+
+### 核心資料表
+- `users` - 用戶管理
+- `criteria_templates` - 評分標準模板
+- `criteria_items` - 評分項目明細
+- `projects` - 評審專案
+- `project_files` - 專案文件
+- `project_websites` - 專案網站連結
+- `evaluations` - 評審記錄
+- `evaluation_scores` - 評分結果明細
+- `evaluation_feedback` - AI 評語和建議
+- `system_settings` - 系統設定
+
+### 關聯關係
+- 用戶 → 多個評分標準模板
+- 評分標準模板 → 多個評分項目
+- 用戶 → 多個專案
+- 專案 → 多個文件/網站連結
+- 專案 → 一個評審記錄
+- 評審記錄 → 多個評分結果
+- 評審記錄 → 多個評語建議
+
+## 預設數據
+
+系統會自動建立：
+- 預設評分標準模板
+- 5個預設評分項目（內容品質、視覺設計、邏輯結構、創新性、實用性）
+- 系統設定參數
