I can't be more specific at this remove, as it's a while since I set Isso up. But I found the documentation pretty unhelpful in places and, when I visited Github to chase up on some of the issues I was having, I came away with the impression, from your replies to existing issues, that your reflex position was to "blame the user" [in pretty grouchy language, in some cases], rather than to accept that your documentation could have been clearer.
