In what way did they kill the Jews in the Holocaust?

Hitler toutred people in many horiffic ways that i would rather not talk about. But his Police (SS) would use ther dogs, hang them, drown, starve, burn, freeze, perform surgery on them while they were awake, poision them, etc.

He also would keep certain people for work mostly the men. They would stay in bug,disease filled bunks with different people. They had to carry dead bodys from one place to another.
