Hey @edmorley sorry about that, I was on PTO for the last two weeks! Looking at it now.

Hey @edmorley ,

Based on the details you provided in #6 should we also add setuptools and wheel to requirements.txt?

Thanks for the PR! :-)

From IRC for posterity:

emorley: I think that typically adding setuptools/wheel to the app's requirements.txt is considered not best practice, since they are needed before installing the requirements (eg during python/pip bootstrap)
emorley: the pip install script installs both
pmoore: ah cool
pmoore: then i'll land it!
