--- title: "Front Matter" date: 2020-08-12 draft: false description: "All the front matter variables available in Congo." slug: "front-matter" tags: ["front matter", "config", "docs"] showDate: false showAuthor: false --- In addition to the [default Hugo front matter parameters](https://gohugo.io/content-management/front-matter/#front-matter-variables), Congo adds a number of additional options to customise the presentation of individual articles. All the available theme parameters are listed below. Front matter parameter default values are inherited from the theme's [base configuration](/docs/configuration/), so you only need to specify these parameters in your front matter when you want to override the default. |Name|Type|Default|Description| | --- | --- | --- | --- | |`externalUrl`|string|_Not set_|If this article is published on a third-party website, the URL to this article.
