Not yet — and the reason matters.
Documenting the embed is the same act as freezing it. The moment this page describes an option, a callback or a version number, somebody builds against it and we owe them that shape for years. We have not finished deciding what we are willing to owe.
What will be on this page, once we can keep the promise.
The one line you paste
The snippet is the same for all three doors. It points at your project, not at a frozen version.
What you can pass in
Every option, with what happens if you leave it out.
What you get back
The callbacks your page can listen to, and the shape of what each one hands you.
What each version number versions
There is more than one, they do not mean the same thing, and saying so here is part of the contract.
