 ### `delayed_attach` accepts an optional hash with the following options:
 - `required`: If set to `true`, the `photo` or the `photo_tmp` will be required before saving.
 - `use_filename`: If set to `true`, the image filename will be used as the name of uploaded file instead of the hash-key used by `activestorage`
+- `variant_info`: (Hash) Variant information to be performed before uploading the file.
 
 ### Examples to upload files in background

-## Preprocessing original files before uploading (Rails 7+)
-```ruby
-class User < ApplicationRecord
-  has_one_attached :photo do |attachable|
-    attachable.variant :default, strip: true, quality: 70, resize_to_fill: [200, 200]
-  end
-end
-```
-`:default` variant will be used to pre-preprocess the original file before uploading (if defined). By this way you have your desired image size and quality as the original image.
