 ## Configure Title Case
 
 Set `titleCaseStyle` to specify the title style used by the [title](/functions/title/) template function and the automatic section titles in Hugo. It defaults to [AP Stylebook](https://www.apstylebook.com/) for title casing, but you can also set it to `Chicago` or `Go` (every word starts with a capital letter).
