To install: Put the pre-packed PBO in your "@ExileServer\addons" directory. It should be alongside "exile_server" and "exile_server_config".

If you are using infiSTAR and want to keep "_CGM = true;", then set "_UMW = true;", and add "DMS_MissionMarkerCircle","DMS_MissionMarkerDot" to "_aLocalM", so your "_aLocalM" would look like: _aLocalM = ["DMS_MissionMarkerCircle","DMS_MissionMarkerDot"];

OPTIONAL: Download the a3_dms folder and edit the config.sqf to your preferences. Repack the a3_dms folder with a PBO tool and follow the "To install:" steps :D

HEADLESS CLIENT: Add this code to the TOP of your initPlayerLocal.sqf

if (!hasInterface && !isServer) then { 1 spawn { waitUntil {player==player}; DMS_HC_Object = player; publicVariableServer "DMS_HC_Object"; }; };
