I've started to add the match schedule (the group phase) -
see /2020--europe/euro.txt  - for the upcoming
Euro 2021 / European Football Championship 2021, June 11th to July 11th.
$ sportdb new euro2021
to build yourself a fresh copy, that is, reading in the match
schedule in the Football.txt format
into a local single-file SQL(lite) database.
New to the (open data) sportdb gem family? See the getting started
guide / project docu .
Cheers. Prost. Enjoy the beautiful game.
PS: If you know other (open) data sources or scripts about the Euro
2021, please tell!
