Link to ISO codes not helpful

[stkjj]

The link for the explanation of ISO Codes despite refering to the ISO.org website is not really helpful as I brings you to a general overview where one has to identify the correct link for the list. It would be better to link directly to this list https://www.iso.org/obp/ui/#search or even make use of the wikipedia-entry https://en.wikipedia.org/wiki/List_of_ISO_3166_country_codes
