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]({{< ref "configuration" >}}), so you only need to specify these parameters in your front matter when you want to override the default.
