Docs on the CLI or the JS API?

Hi there! I just stumbled upon this library recently and it looks excellent — are there any public-facing docs on the CLI or the JS API?

If you're accepting external contributors for documentation, let me know. I'd be happy to at least help set up some sort of doc generation process (e.g., based on the JSDocs) — I want to be mindful of not adding on to the maintenance burden 🙂 thanks!
