Question about "languagecode"?

Hello! The parameter “languagecode” what values can take except “en-us”?

en-us is the default value. You can change it in the config file to any language code / string you want:

languageCode = "pt-BR"

There’s a handy search tool for language codes you can use to find more codes. Usually it’s a two-letter acronym representing a language, ie. en, followed by a dash, followed by a region indicator, ie. us, where en-us means “English as used in the United States”.
