 ## Usage
-The field instantiates similarly to `UploadField`, taking the name of the file relationship and a label, as the first two arguments. Once instantiated, there are many ways to configure the UI.
+The field instantiates similarly to `UploadField`, taking the name of the file relationship and a label, as the first

 ```php
 FileAttachmentField::create('MyFile', 'Upload a file')
   ->setView('grid')
 ```
 
-If the form holding the upload field is bound to a record, (i.e. with `loadDataFrom()`), the upload field will automatically allow multiple files if the relation is a `has_many` or `many_many`. If the form is not bound to a record, you can use `setMultiple(true)`.
