Documentation of new [params.author] parameter

It there a documentation for the new [params.author] or [params.authors] configuration parameter? Best would be a documentation with a full example. Currently I don’t even know the correct spelling as both [params.author] and [params.authors] was suggested.

Can I now set up multiple authors or is it still only one?

Currently I use the congo theme with the following author configuration:

[author]
  name				= 'Martin Krischik'
  email				= 'krischik@users.sourceforge.net'
  image				= 'images/Google-Avatar.png'
  links				= [
    { minds    = "https://www.minds.com/krischik"	    },
    { mewe     = "https://mewe.com/martinkrischik"	    },
    { steemit  = "https://steemit.com/@krischik"	    },
    { hive     = "https://hive.blog/@krischik"		    },
    { blurt    = "https://blurt.blog/@krischik"		    },
    { twitter  = "https://twitter.com/martin_krischik"	    },
    { facebook = "https://www.facebook.com/martin.krischik" },
    { youtube  = "https://youtube.com/@Martin.Krischik"	    }
  ]

If the Congo theme is responsible for rendering author information, you’ll need to work with the theme author as they transition away from .Site.Author in the coming months.
