PYroMat's documentation lives in Python's in-line help text and in HTML, here. For users that already have a minimal familiarity with Python, the introductory tutorial is the right place to start. For intermediate users who might be tinkering with the best way to solve specific problems, the how-to pages are a great resource for a quick nudge in a productive direction. For advanced users, the API documentation goes into gritty detail.
I do my best to always keep the documentation helpful and up-to-date. That said, I am but mortal. If the online docs should ever contradict the in-line help, always trust the in-line help. It is updated with each release.
I still offer the legacy documentation as well.
