[otrs] Otrs quick start manual

Hi I'm new in the otrs project I've installed it and examine the manual However i'm missing basic steps to start to work with this nice tool and see how work basic functions ( something like quick start guide ) Manual is prety nice described but it is bit huge with all these features and options. All I did was I've created new agent and customer. I assigned agent to the grup users. But I don't know what is the next steps to see it in the action. I have created new ticket but it's appeared nowhere Thanks a lot for your answers pet
