-```
-
-The `RecordsUploads::Concern` concern will create an `Upload` entry for every file stored by a `GitlabUploader` persisting the dynamic parts of the path using
-`GitlabUploader#dynamic_path`. You may then use the `Upload#build_uploader` method to manipulate the file.
-
-## Object Storage
-
-By including the `ObjectStorage::Concern` in the `GitlabUploader` derived class, you may enable the object storage for this uploader. To enable the object storage
-in your uploader, you need to either 1) include `RecordsUpload::Concern` and prepend `ObjectStorage::Extension::RecordsUploads` or 2) mount the uploader and create a new field named `<mount>_store`.
-
-The `CarrierWave::Uploader#store_dir` is overriden to
-
- - `GitlabUploader.base_dir` + `GitlabUploader.dynamic_segment` when the store is LOCAL
- - `GitlabUploader.dynamic_segment` when the store is REMOTE (the bucket name is used to namespace)
-
-### Using `ObjectStorage::Extension::RecordsUploads`
-
-> Note: this concern will automatically include `RecordsUploads::Concern` if not already included.
-
-The `ObjectStorage::Concern` uploader will search for the matching `Upload` to select the correct object store. The `Upload` is mapped using `#store_dirs + identifier` for each store (LOCAL/REMOTE).
-
-```ruby
-class SongUploader < GitlabUploader
-  include RecordsUploads::Concern
-  include ObjectStorage::Concern
-  prepend ObjectStorage::Extension::RecordsUploads
-
-  ...
-end
-
-class Thing < ActiveRecord::Base
-  mount :theme, SongUploader # we have a great theme song!
-
-  ...
-end
-```
-
-### Using a mounted uploader
-
-The `ObjectStorage::Concern` will query the `model.<mount>_store` attribute to select the correct object store.
-This column must be present in the model schema.
-
-```ruby
-class SongUploader < GitlabUploader
-  include ObjectStorage::Concern
-
-  ...
-end
-
-class Thing < ActiveRecord::Base
-  attr_reader :theme_store # this is an ActiveRecord attribute
-  mount :theme, SongUploader # we have a great theme song!
-
-  def theme_store
-    super || ObjectStorage::Store::LOCAL
-  end
-
-  ...
-end
-```
