-## How it works
+## 工作原理
 
-When the user clicks the "comment search" button, a modal will open and fetch all comments. The user can then input a keyword to search for specific comments. Once the fetching process is complete, only the comments that include the keyword will be displayed in the modal.
+脚本会在 Bilibili 视频页的评论区添加“搜索评论”按钮，用户点击时，将打开对话框并获取所有评论。在对话框中，用户可以输入关键词并按下 <kbd>Enter</kbd> 来搜索特定评论。评论获取完成后，包含关键字的评论会显示在对话框中。
 
-## Limitation
+## 限制
 
-To improve performance and avoid hitting rate limits, currently only 20 pages of comments will be loaded, which is equivalent to 20 * 49 comments, along with a maximum of 3 sub-comments per comment.
+为了提高性能并避免达到请求速率的限制，目前仅会加载 20 页评论，即 20 \* 49 条评论，以及每条评论的最多 3 条子评论。
