I've been searching around and reading documentation. There are tons of mentions of each of these words:
compositedecompositing composite inputsexoskeletonsdata adaptersworking with duffles
There is a lot of documentation on the technical aspects of these. Like what a duffle selector is and that if it is set to an underscore, what that means for the projection.
What doesn't exist is documentation that shows concise examples and a set of what-ifs. This is hard to find, if it does exist.
