+### Changes
+* [#92](https://github.com/cleverage/flysystem-process-bundle/issues/92) Documentation: the storages are configured with the format of league/flysystem-bundle 3.5 and later (the adapter being the key of its options), the `adapter` / `options` format being deprecated since flysystem-bundle 3.5; the former format is mentioned for an earlier version.

+This is the format of league/flysystem-bundle 3.5 and later, the adapter being the key of its options. With an
+earlier version, use `adapter: 'local'` and `options:` (deprecated since flysystem-bundle 3.5).
+
 Paths used and returned by the tasks are relative to the root of the storage (`directory` or `root` option).
 Listings (`file_pattern` options, [ListContentTask](reference/tasks/list_content_task.md)) are not recursive: to work
 in a sub-directory, configure a dedicated storage whose root is this directory.
