How would I create a hint from a script?

I am attempting a launch procedure script that will launch a rocket fired from explosions with the DestroyJointRadiusPercent feature and am wondering is it possible to make it add a hint at the top of the screen saying it is ready to launch and when it has launched?

Here is the code for it that I have so far:

print("Script Active. Waiting Launch.") --Notification to the console that it is active and ready.

Main = game.Workspace.Rocket.RocketModel.Head
Booster = game.Workspace.Rocket.RocketModel.Booster

function onClicked()
	explosion = Instance.new("Explosion")
	explosion.BlastRadius = 50
	explosion.BlastPressure = 1000
	explosion.DestroyJointRadiusPercent = 0
	explosion.Position = Booster.Position
	explosion.Parent = game.Workspace
	wait(1)
	explosion = Instance.new("Explosion")
	explosion.BlastRadius = 50
	explosion.BlastPressure = 1000
	explosion.DestroyJointRadiusPercent = 0
	explosion.Position = Booster.Position
if
	Main.Velocity.y > 10000
	then
	wait(2)
	explosion = Instance.new("Explosion")
	explosion.BlastRadius = 50
	explosion.BlastPressure = 750
	explosion.DestroyJointRadiusPercent = 0
	explosion.Position = Booster.Position
else
	explosion = Instance.new("Explosion")
	explosion.BlastRadius = 50
	explosion.BlastPressure = 5000
	explosion.DestroyJointRadiusPercent = 0
	explosion.Position = Booster.Position
repeat
	
until Main.Velocity.y > 21000
	wait(5)
	if Main.Velocity.y > 20000
		then
		wait(5)
		explosion = Instance.new("Explosion")
		explosion.BlastRadius = 50
		explosion.BlastPressure = 2500
		explosion.DestroyJointRadiusPercent = 0
		explosion.Position = Booster.Position
	else
		explosion = Instance.new("Explosion")
		explosion.BlastRadius = 50
		explosion.BlastPressure = 4750
		explosion.DestroyJointRadiusPercent = 0
		explosion.Position = Booster.Position
	end
end
end
script.Parent.ClickDetector.MouseClick:connect(onClicked)

local h Instance.new("Hint",Workspace) h.Text = "This will be a hint"--Change the "This will be a hint" to anything you like
wait(2)--The time between the hints to be displayed
local h Instance.new("Hint",Workspace h.Text = "This will be another hint"--Change the "This will be another hint" as well.
