+## 注意事项
 为了方便助教检查，将此注意事项放在最前面：
 - 有关功能中的查重:
-
-实现了双重查重机制：
-
-内存级查重 - 当前会话中生成的题目查重
-文件级查重 - 历史生成的所有题目查重
-主要代码在 AbstractQuestionGenerator 类和FileServiceImpl中：
 - 测试时的java-version; java version "23" 2024-09-17
   Java(TM) SE Runtime Environment (build 23+37-2369)
   Java HotSpot(TM) 64-Bit Server VM (build 23+37-2369, mixed mode, sharing)

+## 扩展指南
+
+### 添加新的难度级别
+1. 在`DifficultyLevel`枚举中添加新级别
+2. 在`QuestionFactory`中实现对应的题目生成逻辑
+3. 在`AuthServiceImpl`中添加测试用户
+
+### 自定义题目类型
+继承`AbstractQuestionGenerator`并实现：
+```java
+@Override
+protected String generateQuestionContent(DifficultyLevel level) {
+    // 自定义题目生成逻辑
+}
+
+@Override
+protected String generateFallbackQuestion(DifficultyLevel level) {
+    // 自定义备用题目
+}
+```
+
+## 注意事项
+
+1. **文件权限**：确保程序有写入`exam_papers`目录的权限
+2. **题目数量**：每次生成10-30道题目
+3. **查重范围**：查重仅限于同一用户的题目历史
+4. **会话管理**：退出程序后内存中的查重记录会清空
+
+## 故障排除
+
+### 常见问题
+1. **文件保存失败**：检查磁盘空间和目录权限
+2. **登录失败**：确认用户名密码正确（注意空格分隔）
+3. **题目重复**：系统会自动尝试生成不重复的题目
 
+### 日志查看
+程序运行日志和错误信息会直接输出到控制台。
