Expected Result

Should work, no changes since this working build. Last time when I had issues I spent hours and hours trying to debug it before finding out it was an issue with the git checkout commands that seems to have affected everyone. So this time I'm just filing a bug right away, sorry if it is something on my end!

python -m sphinx -T -E -b html -d _build/doctrees -D language=en . $READTHEDOCS_OUTPUT/html
