My netlify site is liisaknuuti.netlify.app. I (or actually my granma) has a domain liisaknuuti.fi and that is bought from a Finnish company. We don’t want to pay to the Finnish company anymore so what I would like to do is make Netlify my domain provider. They gave me some sort of a key that should make the transition possible but I can’t figure out where to put it and is this even possible.
Sorry for possibly inexact terminology and thanks for your answer
