How do I save the points value in this code?

local intv = 1
local pointsGiven = 1

-------------------------------------------

game.Players.PlayerAdded:connect(function(player)
    local leaderstats = Instance.new("Model")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player
	
    local Points = Instance.new("IntValue")
    Points.Name = "Points"
    Points.Value = 0
    Points.Parent = leaderstats
end)

while wait(intv) do 
    for _, player in ipairs(game.Players:GetPlayers()) do
        if player:FindFirstChild("leaderstats") then
			
            player.leaderstats.Points.Value = player.leaderstats.Points.Value + pointsGiven
        end
    end
end

I know, DataStores, but I can't figure out the actual code.
