They do have a number of videos on YouTube. However, I have not found a user guide or anything like that.
In the program, there is a Feedback button (email envelope icon). I had a question about one of their tasks and sent the email and got a quick reply. Don't forget, they are in Australia, so reply time is based on time zones. I am in the central US and sent my email around 3pm and had a reply when I came into work in the morning.
