-请编辑目录下的php文件：
+请在图片根目录下，创建文件**README_copyright.txt**，内容参考下面示例代码：
+
 ```
-themes/beauty/views/layout/
+<span>&copy;2022 - 2024</span>
+by <a href="https://filesite.io/" target="_blank">FileSite.io</a>
+<br>
+执行耗时: {page_time_cost} ms

-找到“尾部网站信息”，按自己的需要修改并保存。
-
-注意本地保存相关文件存档，machete升级系统时会覆盖此目录下的文件。
