Temporary content while app is loading

Hi, I’m looking for a link to an article I found in Meteor API Docs or Meteor Guide before but cannot seem to find anymore.

It showed example code of how you can display some temporary html client-side while a user is loading an app for the first time.

Any pointers to where that article might have gone, or if someone knows the code to do it, it would be very much appreciated.

Many thanks.

For anyone else who is looking for it, I finally managed to find it here:
