Geographically, the league currently covers Dumfries and Galloway although clubs have also been located in East Ayrshire and South Lanarkshire.
The winners take part in an end of season promotion play-off with the East of Scotland Football League and West of Scotland Football League champions, subject to clubs meeting the required licensing criteria.
In seasons where league membership has been low, clubs have played each other four times, instead of the usual twice.
The final is usually contested by the winners of two mini-leagues, but has also been played as a straight knock-out competition.
Creetown, Dalbeattie Star, Newton Stewart, St Cuthbert Wanderers, and Wigtown & Bladnoch are full members of the Scottish Football Association therefore enter the Scottish Cup, as do the winners of the league.
