If you're not using Dash, Velocity, or Zeal as a docset manager, I highly recommend grabbing them immediately.
I've made docsets for Blender, Hiero, and PyMel and they're available through the Dash-User-Contributions.
The source for them is also available below:
Note: PyMel is for version 1.0.7, and the latest version is 1.0.8 in Maya 2016. They've changed something with their docs and I haven't figured out how to generate the docset. I'll update it when I can figure out how.
