 Each storage backend can have options the admin can set in admin page.
+To make the options possible, you need to implement the `Friendica\Model\Storage\IStorageConfiguration` interface.

+All methods in the interface must be implemented:

 - `getOptions()` returns an array with details about each option to build the interface.
 - `saveOptions(array $data)` get `$data` from admin page, validate it and save it.
