How can I make my punch animation do damage?

humanoid = game.Players.LocalPlayer.Character:WaitForChild("Humanoid")
right = script:WaitForChild("RightPunch")
left = script:WaitForChild("LeftPunch")
idle = script:WaitForChild("Idle")
enabled = false
Mouse = game.Players.LocalPlayer:GetMouse()

Mouse.KeyDown:connect(function(key)
	if key == 'y' then
		local anim = humanoid:LoadAnimation(idle)
		if enabled == false then
			print ('Stance Enabled')
			anim:Play()
			enabled = true
		elseif enabled == true then
			anim:Stop()
			enabled = false
		end
	end
	
	if key == 'e' then 
		local anim = humanoid:LoadAnimation(right)
		if enabled == true then
			anim:Play()
			wait(0.6)
		else
			print('Not in stance')
		end
	elseif key == 'q' then
		local anim = humanoid:LoadAnimation(left)
		if enabled == true then
			anim:Play()
			wait(0.6)
		else
			print('Not in stance')
		end
	end
	
end)

What do I add to this to make it do damage?

LocalScript :

game.Players.LocalPlayer.Character:WaitForChild("RightHand").Touched:Connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") and not db and not damage and hit.Parent.Humanoid ~= game.Players.LocalPlayer.Character.Humanoid then
        if game.Players.LocalPlayer.Character.Humanoid.Health > 0 then
            damage = true
            game.ReplicatedStorage.Punch:FireServer(hit.Parent.Humanoid) --your remote event
        end
    end
end)

You will need to create a RemoteEvent

In the ServerScript you write something like :

 game.ReplicatedStorage.Punch.OnServerEvent:Connect(function(plr , hit)

hit:TakeDamage(10)

end)
