What is a good workflow for a loading screen?

I want to make an effective loading in my game, as the way i have done before was very convoluted. Previously, i had an starter GUI load in a frame that covers the entire screen, then a local script with content provider syncing with animations so they wouldnt lag the first time they played. Then after it did that, it would make a button appear and once clicking it, a remote signal would be sent to the server and the appropriate scripts be enabled.
Is there a better way to do it?

Drop this modified script in ReplicatedFirst … It’s wonderful!
Intro.rbxm (2.6 KB) You can change how long it is up in Intro …

edit: I see I left a rem in there I meant to take out after testing. My real one has many intros.
This came from Roblox Command help (with a few modifications).
