How do I use Humanoid.StateChanged?

Hello. I’ve been searching how to use Humanoid.StateChanged but I couldn’t find any examples of how to use it, and my attempts on using it have failed. I want to use this function to detect if a player started climbing, jumping, or if the player landed.
I tried using it in two ways:

humanoid.StateChanged:Connect(function()
	if humanoid.StateChanged == Enum.HumanoidStateType.Climbing then
		if humanoid.GetState(Enum.HumanoidStateType.Climbing) == true then
			print("climbing")
		end
	end
end)

humanoid.StateChanged:Connect(function(climbing)
	if climbing == Enum.HumanoidStateType.Climbing then
		if climbing == true then
			print("climbing")
		end
	end
end)

Neither worked. I would like to know how to use it correctly. Thanks in advance.

Edit 1: I found a few examples in the documentation for the Humanoid, but I don’t understand how it works.

Humanoid.StateChanged

local function onStateChanged(_oldState, newState) -- here, two arguments
	if newState == Enum.HumanoidStateType.Climbing then -- check newState
		print("climbing")
	end
end

humanoid.StateChanged:Connect(onStateChanged)

first, the function receives two arguments. the _oldState and the newState.
you are most likely interested in the newState, so you need both arguments.

Humanoid:GetState()
second, of course you can also just use humanoid:GetState() to retrieve the current state. notice we use colon : for the call.

local function onStateChanged()
	local newState = humanoid:GetState()
	if newState  == Enum.HumanoidStateType.Climbing then
		print("climbing")
	end
end

humanoid.StateChanged:Connect(onStateChanged)

if you understand these, try to check and compare with the examples in the documents for better understanding of syntax

Thank you. It makes sense to me now. The “StateChanged” function is most relevant for what I would like to do right now.
