Configuration
Table of Contents
Congo is a highly customisable theme and uses some of the latest Hugo features to simplify how it is configured.
The theme ships with a default configuration that gets you up and running with a basic blog or static website.
Configuration files bundled with the theme are provided in TOML format as this is the default Hugo syntax. Feel free to convert your config to YAML or JSON if you wish.
The default theme configuration is documented in each file so you can freely adjust the settings to meet your needs.
config/_default/ folder of your Hugo project and delete the config.toml file in your project root.Site configuration #
Standard Hugo configuration variables are respected throughout the theme, however there are some specific things that should be configured for the best experience.
The site configuration is managed through the config/_default/config.toml file. The table below outlines all the settings that the Congo takes advantage of.
Note that the variable names provided in this table use dot notation to simplify the TOML data structure (ie. outputs.home refers to [outputs] home).
| Name | Default | Description |
|---|---|---|
theme | "congo" | When using Hugo Modules this config value should be removed. For all other installation types, this must be set to congo for the theme to function. |
baseURL | Not set | The URL to the root of the website. |
defaultContentLanguage | "en" | This value determines the default language of theme components and content. Refer to the language and i18n section below for supported language codes. |
enableRobotsTXT | true | When enabled, a robots.txt file will be created in the site root that allows search engines to crawl the entire site. If you prefer to provide your own pre-made robots.txt, set to false and place your file in the static directory. For complete control, you may provide a custom layout to generate this file. |
paginate | 10 | The number of articles listed on each page of the article listing. |
summaryLength | 0 | The number of words that are used to generate the article summary when one is not provided in the front matter. A value of 0 will use the first sentence. This value has no effect when summaries are hidden. |
outputs.home | ["HTML", "RSS", "JSON"] | The output formats that are generated for the site. Congo requires HTML, RSS and JSON for all theme components to work correctly. |
permalinks | Not set | Refer to the Hugo docs for permalink configuration. |
taxonomies | Not set | Refer to the Organising content section for taxonomy configuration. |
Language and i18n #
Congo is optimised for full multilingual websites and theme assets are translated into several languages out of the box. The language configuration allows you to generate multiple versions of your content to provide a customised experience to your visitors in their native language.
The theme currently supports the following languages by default:
| Language | Code |
|---|---|
| 🇬🇧 English | en |
| 🇧🇩 Bengali | bn |
| 🇨🇳 Chinese | zh |
| 🇫🇮 Finnish | fi |
| 🇫🇷 French | fr |
| 🇩🇪 German | de |
| 🇮🇱 Hebrew | he |
| 🇭🇺 Hungarian | hu |
| 🇮🇹 Italian | it |
| 🇯🇵 Japanese | ja |
| 🇧🇷 Portuguese (Brazil) | pt-br |
| 🇵🇹 Portuguese (Portugal) | pt-pt |
| 🇷🇴 Romanian | ro |
| 🇪🇸 Spanish (Spain) | es |
| 🇹🇷 Turkish | tr |
The default translations can be overridden by creating a custom file in i18n/[code].yaml that contains the translation strings. You can also use this method to add new languages. If you’d like to share a new translation with the community, please open a pull request.
Configuration #
In order to be as flexible as possible, a language configuration file needs to be created for each language on the website. By default Congo includes an English language configuration at config/_default/languages.en.toml.
The default file can be used as a template to create additional languages, or renamed if you wish to author your website in a language other than English. Simply name the file using the format languages.[language-code].toml.
defaultContentLanguage parameter in the site configuration matches the language code in your language config filename.| Name | Default | Description |
|---|---|---|
languageCode | "en" | The Hugo language code for this file. It can be a top-level language (ie. en) or a sub-variant (ie. en-au) and should match the language code in the filename. Hugo expects this value to always be in lowercase. For proper HTML compliance, set the isoCode parameter which is case-sensitive. |
languageName | "English" | The name of the language. |
displayName | "EN" | The name used when the language appears on the website. |
isoCode | "en" | The ISO language code for HTML metadata purposes. It can be a top-level language (ie. en) or a sub-variant (ie. en-AU). |
weight | 1 | The weight determines the order of languages when building multilingual sites. |
rtl | false | Whether or not this is a RTL language. Set to true to reflow content from right-to-left. Congo fully supports using RTL and LTR languages at the same time and will dynamically adjust to both. |
dateFormat | "2 January 2006" | How dates are formatted in this language. Refer to the Hugo docs for acceptable formats. |
title | "Congo" | The title of the website. This will be displayed in the site header and footer. |
description | Not set | The website description. This will be used in the site metadata. |
copyright | Not set | A Markdown string containing the copyright message to be displayed in the site footer. If none is provided, Congo will automatically generate a copyright string using the site title. |
author.name | Not set | The author’s name. This will be displayed in article footers, and on the homepage when the profile layout is used. |
author.image | Not set | Path to the image file of the author. The image should be a 1:1 aspect ratio and placed in the site’s assets/ folder. |
author.headline | Not set | A Markdown string containing the author’s headline. It will be displayed on the profile homepage under the author’s name. |
author.bio | Not set | A Markdown string containing the author’s bio. It will be displayed in article footers. |
author.links | Not set | The links to display alongside the author’s details. The config file contains example links which can simply be uncommented to enable. The order that the links are displayed is determined by the order they appear in the array. Custom links can be added by providing corresponding SVG icon assets in assets/icons/. |
Menus #
Congo also supports language-specific menu configurations. Menu config files follow the same naming format as the languages file. Simply provide the language code in the file name to tell Hugo which language the file relates to.
Menu config files are named with the format menus.[language-code].toml. Always ensure that the language code used in the menus configuration matches the languages configuration.
The Getting Started section explains more about the structure of this file. You can also refer to the Hugo menu docs for more configuration examples.
Theme parameters #
Congo provides a large number of configuration parameters that control how the theme functions. The table below outlines every available parameter in the config/_default/params.toml file.

Other configuration files #
The theme also includes a markup.toml configuration file. This file contains some important parameters that ensure that Hugo is correctly configured to generate sites built with Congo.
Always ensure this file is present in the config directory and that the required values are set. Failure to do so may cause certain features to fucntion incorrectly and could result in unintended behaviour.
