Question: Deployed two machines in one app?

[wnma3mz]

Thank you for your project, it has been of great use to me.
But I have a confusion, I am not sure if it is a problem with my operation or the script itself.
When I follow the process to step 10 flyctl deploy, the platform shows two machines at the same time. This is shown in the image below:

I made sure I didn't perform any additional operations. I checked the project's scripts and didn't find the problem either. Is there a way to start only one machine? Two machines in the same area seems a bit redundant.

I did the following to shut down a machine.

# Check machine status
fly status
# Stop machine by machine id
fly machine stop $(machine_id)
# Destroy machine by machine id
fly machine destroy $(machine_id)

Thank you @wnma3mz for bringing this up! You are right: since I wrote this README fly changed the default to 2 machines on initial deploy (which I think is the right default for production deploys). I updated the README to mention it: 7d36e75 and 5fea033

Thanks for the reply. But I'm still curious as to what I should do if I want to set only one machine to start by default. Or start three machines by default. I didn't find a place where I can configure it.
