Minecraft TTT explanation?

I'll get my PC over the next few days, and I wanted to ask what TTT is. So the explanation, what roll what and how the game is.

It always depends on which server you play TTT. The classic mode is with Innocents, Traitorn (Traitors) and Detectives. The job of the Innocents and the detectives is to track down the traitors. The traitors' job is to kill all innocents and detectives without getting killed.

On some servers, the Traitor and the detectives have bonus items with which they can buy special items.

Thank you. There's also such a scanner in one place, there's always the right one displayed or eg if you are a Traitor, because go in, and another Traitor presses the button, it will then show that you are Innocent or Traitor anyway ( hopefully you understand that)

The tester will automatically start as soon as a person enters it. Traitors are disarmed by this. However, on some servers there's an item that you can buy, which can fake the tester.
