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.tomlfile 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.

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 out of the box:
|🇬🇧 English (default)|
|🇨🇳 Chinese - Simplified (China)|
|🇹🇼 Chinese - Traditional (Taiwan)|
|🇧🇷 Portuguese (Brazil)|
|🇵🇹 Portuguese (Portugal)|
|🇪🇸 Spanish (Spain)|
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.
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
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

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.

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.
