How do I award 5 Player Points to this player? (HELP)

This code/script shows a gui when you get your first kill. Now, how would I award Player Points(5) to this player?

local plr = game.Players.LocalPlayer

moved = false

while true do
    if moved == false and plr.leaderstats.Kills.Value >= 1 then
        moved = true
        plr.PlayerGui.nicekills.MainFrame.Background.TextLabel:TweenPosition(UDim2.new(0, 0, 4, 0), "Out", "Bounce", 2.5)
        wait(7)
        plr.PlayerGui.nicekills.MainFrame.Background.TextLabel:TweenPosition(UDim2.new(0, 0, 10, 0), "Out", "Bounce", 2.5)
    end
    wait(1)
end
