Hey @crwilcox, we made this change in #103 due to a failure and related documentation around Sphinx-1.4 and greater. We are 1.6.3.

https://github.com/readthedocs/recommonmark

# for Sphinx-1.4 or newer
extensions = ['recommonmark']

# for Sphinx-1.3
from recommonmark.parser import CommonMarkParser

source_parsers = {
    '.md': CommonMarkParser,
}

source_suffix = ['.rst', '.md']

I think I misunderstood how to update this file correctly. Could you PTAL when you have a moment?

Pending fix from googleapis/synthtool#570 Closing for now.
