PL 3.0 integration

[jsheffers]

Are there any instructions with how to get this working with Pattern Lab Node 3.0? I'm using the edition-twig version and it looks like the recommended way to add extensions is through alter-twig.php. How does that relate to how this works? Can this be integrated in 3.0?

I'd like to know this as well.
