  self
end

#register_storage(*storage) ⇒ Object

Registers a storage to be used with content-addressable file. All shrine storages are supported by default, as is any duck type that responds to Storage#open(content-addressable-hash) and Storage#exists?(hash).

Additional functionality needs Storage#url(hash), Storage#delete(hash) and Storage#download(hash).

When a content-addressable file is deleted, it’s deleted from all registered storages. use #register_read_only_storage to prevent deletion.
