Tapping on the question Mark icon to the right of the Orthographic views will open up the uMake Help panel. Here you can find videos to help you get started with uMake or help refresh your memory about a certain function in case you need a refresher.
Essentially you can access help videos and tutorials/ Courses right from within the editor, and then follow along in the editor if you want.
Tapping on any of the videos will open up a video player right in the editor. You can move and resize this player anywhere in the editor to make it easy to follow along.
