Flightly is a massively popular flight-tracking app with a gorgeous UI (not affiliated or sponsored). Their website has a similar focus on pixel-perfect design. The site is built in Framer and it's almost certain the help page (https://flighty.com/help) is powered by the Content Management System. So just like you can go in and post an update to your course members, Flightly can update their Help section in seconds via the dead-simple interface.
