+To support multilingualism the configuration above needs to be extended by parameters for the specific languages.
+Each `language` section overrides default site's parameters when that language is chosen.

+DefaultContentLanguage = "en" # needs to match one of the language sections, add this at the main section of the configuration
+
+[params] # add this to theme params, do not duplicate tables
