 @TomAugspurger @jorisvandenbossche  Thanks! Can you check http://pandas-docs.github.io/pandas-docs-travis/generated/pandas.read_csv.html#pandas.read_csv in a few hours to see if it now is correctly displaying? Will do, just set a reminder. I checked it locally, but will take a look at the resulting production documentation later today.

Edit: It looks just fine.
