Problem with behavior tree

Hi folks today I’ve come with problem on behavior tree, I’ve started to learning it about a one week ago and its pretty hard for me cause there isn’t much information in internet about it. so I have several questions long story short i’am trying to write a dialogue system with behavior tree. I already know about tasks and services and how can i create and use them what I dont know is how to create composit nodes can?
