Well, I am not exactly sure what bot you are using, but I am guessing it has a auto-respond feature. When people (or what have you) come in, have the opening message say something like, "Click on my profile for help or whisper 'help' to me." Then for the auto-reply, just have more informational options that can be set off by user input. It is quite simple actually. I hope this helps.
