+## Languages for spell checking
+
+To change default languages for spell checking, add or remove language-codes (and optionally country code) from the DICTIONARIES-list when configuring your app. Consult list of [language codes](https://en.wikipedia.org/wiki/List_of_ISO_639_language_codes) and [country codes](https://en.wikipedia.org/wiki/List_of_ISO_3166_country_codes). For example:
