To build a local copy of the pydata-google-auth docs, install the programs in requirements-docs.txt and run 'make html'. If you use the conda package manager these commands suffice:

git clone git@github.com:pydata/pydata-google-auth.git
cd pydata-google-docs/docs/source
conda create -n pydata-google-auth-docs --file ../requirements-docs.txt
source activate pydata-google-auth-docs
make html
open _build/html/index.html
