+[epic_games]
+enabled=true #On windows this is default true, on linux default false
+location="C:\ProgramData\Epic\EpicGamesLauncher" #If this value is not defined, the tool will try to find it automatically (only windows). If it can't find it, it will fail and tell you.
+
+[legendary]
+enabled=false #On windows this is default false, on linux default true
+executable="legendary" #If this value is not defined, "legendary" will be used, it is assumed to be on the path.
+
+[steam]
+location="C:\\Program Files (x86)\\Steam\\" #If this value is not defined, the tool will try to find it automatically. If it can't find it, it will fail and tell you.
+
+[steamgrid_db]
+enabled = true #If false, the whole download of custom art will be skipped.
