 ### Loader
 
-The Loader is used to initally create the CSPBuilder object with a given set of data. You skip that, forward a file to load, provide an array or [use the default loader file](https://github.com/getkirby/kirby/blob/master/loader.json). Using a custom file is recommended when for example adding additional font-src for google web fonts.
