Training that lives inside your product

You are looking at Underlayer rendering a course about Underlayer. Everything on the screens that follow is a real block type doing its real job — no screenshots, no mock-ups. If a thing works here, it works in your product, because it is the same player.

Worth knowingThis course is also the seed. Any workspace can create a copy of it from New course → Use the demo course, then take it apart block by block to see how each screen was built.
