The linux firmware creation process does not match the video uploaded here. I have more questions that I don't know how to answer

I have doubts about the question in the image and the following questions:
Do you want to download the firmware [y] or use an available firmware [n]?
Enter the BTICINO root password (pwned123):
Do you want to create an SSH key [y] or use your SSH key [n]? (y/n):
Do you want to remove Sig files [y] or keep them [n]? (y/n):
Do you want to install MQTT [y] or no [n]? (y/n):
Do you want to be notified when a new firmware is available [y] or not [n]? (y/n):
thanks
