How do you make a local script not go again on reset?

I have a script like this

wait(5)

   game.Workspace.Server:Play()
 game:GetService("StarterGui"):SetCore("ChatMakeSystemMessage", {                  
 
  Text = "[Server] Hello, Welcome to Urban street Runway!"; 
  Color = Color3.fromRGB(255, 255, 255);
  Font = Enum.Font.Highway;
  FontSize = Enum.FontSize.Size12;

})

But when someone resets it does it again please help

Place it in game.StarterPlayer.StarterPlayerScripts.
