 | `ogImage`             | Your default OG image for the site. Useful for social media sharing. OG images can be an external image url or they can be placed under `/public` directory.                                                                                        |
 | `lightAndDarkMode`    | Enable or disable `light & dark mode` for the website. If disabled, primary color scheme will be used. This option is enabled by default.                                                                                                           |
+| `postPerIndex`        | The number of posts to be displayed at the home page under `Recent` section.                                                                                                                                                                        |
 | `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. |
