Thanks, @fnattino. Shouldn't we add the doi to DESCRIPTION too?

Good point! I have added the Zenodo DOI to the CITATION.cff file, but could not find a field where to specify the within the DESCRIPTION file? Maybe this is because on CRAN all packages are automatically assigned the CRAN DOI?

Sorry, I meant the Zenodo link (containing the DOI), as you did for rcoins: https://github.com/CityRiverSpaces/rcoins/blob/1372a92665277f17daf3ea3dadffb0c8001f4cba/DESCRIPTION#L22

Or maybe it is better to leave out the Zenodo link to avoid confusion with the DOI from CRAN? (Btw, is it okay to have two DOIs on the same publication?)
