-**Note:** As you have read earlier, the `Updater` runs in a seperate thread. That is very nice for this tutorial, but if you are writing a script, you probably want to stop the Bot by pressing Ctrl+C or sending a signal to the Bot process. To do that, use `updater.idle()`. It blocks execution until one of those two things occur, then calls `updater.stop()` and then continues execution of the script.
