DKP comes down to using raidpoints.
Raidpoints are earned by joining raids.
You will earn points for signing up, joining raid, killing a boss, etc..
This system will reward the players that are most active raiding, since they build up more points.
These points can be used to claim rewards.
E.g. You build up 30 points, you can use these to claim a T2 helm, if no one else offers more raidpoints for it.
