 ## Creating ACF fields
 Once a block is created you'll be able to assign ACF fields to it using the standard Custom Fields interface in WordPress. We recommend using [sage-advanced-custom-fields](https://github.com/MWDelaney/sage-advanced-custom-fields) to keep your ACF fields in version control with Sage.
