+2. Then he should receive the `registered_as_admin`-event and is successfully registered as an admin, but he could also
+   receive the self-explaining `already_registered_as_admin`, which means, that an admin already exists.
+   The `registered_as_admin`-event contains the quiz.
+3. If players join, the `player_joined`-event will be emitted with the username of the user who joined
+4. The admin can now set the index of the question which sould be show on the player-screen with
+   the `set_question_number`-event.
+5. Now, the admin can emit the `get_question_results`-event to show the results of the question-index which is sent with
+   this event, on the screen of the users and on its own.
+6. The response of the `get_question_results`-event is the `question_results`-event, containing the results.
+
+> Note: Most of these events require some kind of data.
