This is an update for the Belarus definition. This update uses the league structure used in Belarus for the 2019/20 season..
All team names used in this definition are real team names, as used for the 2019/20 season and any reserve/B teams have been removed, in which case a league would run with a smaller number of teams. The reason reserve/B teams are removed is that where leagues allow reserve/B teams to compete there is usually a block on those teams being promoted above a certain level and forbids those teams from it's national cup.
