How do I add a leaderboard?

I need help on how to add a leaderboard

Yea here's a good link for you to reference next time.

Here is what the code looks like:

local function onPlayerJoin(player) -- Function adds a folder to the player object: (player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats" -- the folder is always called "leaderstats"
	leaderstats.Parent = player -- then the folder is added to the player object: (player)
 
	--Here is where the stats are named and given values
	local gold = Instance.new("IntValue")
	gold.Name = "Gold"
	gold.Value = 0
	gold.Parent = leaderstats -- They are always parented to the (leaderstats)

	--You can add more stats
	--e.g. experience; points; time played; etc..
end

game.Players.PlayerAdded:Connect(onPlayerJoin)

(If you're going to copy this code, make sure to press "View Source" to copy it correctly, you'll need to make sure this is pasted into a normal script that is parented to the workspace or ServerScriptService)
