Missing help/documentation in PyCharm 4.03 Community Edition

This was reported by someone else, but I couldn't post a reply to that question, so...

I just downloaded pycharm-community-4.0.3.dmg and when I run it via the PyCharm Help menu (Help->?Help Topics) the Mac "Help Center" pops up and says "The selected topic is currently unavailable"

Is there any other documentation for PyCharm available.  I can't find any, and I'd be surprised that the Help menu would be the only source.

Thanks!
