I think you really need a separate pitch and documentation for "technical" and "non-technical" users. The editor system (GUI + Sublime Text integration) is effectively a separate project from the underlying format + library.
This is helpful feedback, thank you. We are working on this possibility, and explaining a clearer separation between, as another poster mentioned, the Python library (which is headless) and a specific implementation (which requires some sort of text view that may have GUI features).
