To add a translation:

3. Translate the values of the "message" and "description" fields for each entry.
4. You can translate language names by adding them to the new locale file. Use the language code as the key (for example: "de": { "message": "Deutsch"}). You can find the full list of language codes in the Polish translation file _locales/pl/messages.json.
