 `OperationDetails` are lines starting with `05`. They aim at providing additional information about the operation.
 Below is the list of additional details available for each operation.
 
-These details can be accessed through `operation.details`, which will provide all the attributes. To fetch a specific attribute, you can use `operation.details.attribute`. For example, `operation.details.unstructured_label`. Ultimately, you can also access the 70 characters of the detail by using its code like `operation.details.mmo`
-All unmapped details can be accessed via `details.unknown` which will return the codes and the corresponding line details.

+All unmapped details can be accessed via `details.unknown` which are stored in a hash with the format `'detail_code' => 'line_detail'`, so
+to get the data for the unknown detail_code `AAA` the call would be `details.unknown['AAA']`.
+
+Object example:
+```
+#<CFONB::Details:0x0000
+ @AAA="UNKNOWN DETAIL INFO",
+ @LIB="MENSUEAUHTR12345",
+ @NPY="INTERNET SFR",
+ @RCN="OTHER REFERENCE                    PURPOSE",
+ @REF="REFERENCE",
+ @client_reference="OTHER REFERENCE",

+ @operation_reference="REFERENCE",
+ @purpose="PURPOSE",
+ @unknown={"AAA"=>"UNKNOWN DETAIL INFO"}

 If you encounter new and relevant ones, please open an issue or a pull request with the appropriate implementation.
 We aimed at making it as easy as possible to add new details. You just need to do the following on initialization:
