The issue I had was I couldn't even work out how to download it
It seems I need to download it to a server for publishing (didn't even know that until I read the book, which arrived today
). All the "homemade" websites I have done in the past have been via self-build sites, but you have to pay quite a lot to add a half decent directory, so it seemed better to spend a tenner on a book and try to suss out how to do it myself with Joomla.
