+
+```
+[nenghui_products_list per_page="9"]
+```
+
+### 2. 在模板文件中使用
+
+在主题模板文件中使用 `do_shortcode()` 函数：
+
+```php
+<?php echo do_shortcode('[nenghui_products_list per_page="9"]'); ?>
+```
+
+### 3. 组合使用多个短代码
+
+可以在同一个页面中使用多个短代码：
+
+```
+[nenghui_banner_title title="我们的产品"]
+[nenghui_products_list per_page="9"]
+[nenghui_contact_form]
+```
+
+### 4. 响应式设计
+
+所有短代码都支持响应式设计，会自动适应不同屏幕尺寸。
+
+### 5. 深色模式
+
+所有短代码都支持深色模式，会自动根据系统设置切换主题。
+
+## 常见问题
+
+### Q: 短代码不显示怎么办？
+
+A: 请确保：
+1. 短代码名称拼写正确
+2. 主题已正确激活
+3. 没有PHP错误（检查调试日志）
+
+### Q: 如何自定义短代码样式？
+
+A: 可以通过以下方式自定义：
+1. 在自定义器中修改相关设置
+2. 使用CSS覆盖默认样式
+3. 修改对应的模板文件
+
+### Q: 短代码参数不生效怎么办？
+
+A: 请确保：
+1. 参数名称拼写正确
+2. 参数值格式正确
