Can you leave 'header' (and skiprows below) with single backticks? (that's how literal references to kwargs are done in the rest of the docstring I think).
For the code example, the double ones are good!

[kokes]

yup, done

[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.
