 | `postPerPage`         | You can specify how many posts will be displayed in each posts page. (eg: if you set SITE.postPerPage to 3, each page will only show 3 posts per page)                                                                                                                                                                                             |
 | `scheduledPostMargin` | In Production mode, posts with a future `pubDatetime` will not be visible. However, if a post's `pubDatetime` is within the next 15 minutes, it will be visible. You can set `scheduledPostMargin` if you don't like the default 15 minutes margin.                                                                                                |
+| `showArchives`        | Determines whether to display the `Archives` menu (positioned between the `About` and `Search` menus) and its corresponding page on the site. This option is set to `true` by default.                                                                                                                                                             |
 | `editPost`            | This option allows users to suggest changes to a blog post by providing an edit link under blog post titles. This feature can be disabled by removing it from the `SITE` config. You can also set `appendFilePath` to `true` to automatically append the file path of the post to the url, directing users to the specific post they wish to edit. |
