First, create the layout for the new bank yourself using the 'File->New bank layout' functionality of StatementReader. It's a very easy interface to use. An illustrated tutorial can be found here.
Next, we would like to hear from you! We are always keen to add more bank layouts to our database. Contact us by email on firstname.lastname@example.org and your new bank layout will be included in our next software update. We will also reward you with free credits for helping us to expand our database.
