no instructions!!

There is no instructions on how to set this app to my imac. I downloaded and paid for these apps for my mac and for my ipad. I also purchase the show & write it host for my ipad. I input the info that was asked for and still nothing. I am sure this is a great app because of its concept but how do i use it? is the question….. also where is the settings tab incase i want to change something?
