I think you would need a very long answer to a question like that, but a short answer would be that we could send your clerks the report on the Scottish independence referendum, which we produced in December 2014. It goes through the whole development of the process, what was done with the question testing, how it was tested, the development of the legislation, and the agreement between the U.K. and the Scottish Parliaments.
That's probably the easiest way of getting it in a concise form.
