How do I create a Gmail SMTP server?

Hello there, I'm curious about something. I've been trying to set up a Gmail SMTP server but I'm having some difficulties. Could you please walk me through the process of creating one? I'd like to know what steps I need to take and what settings I should configure to ensure that it's set up correctly. I'm not too familiar with technical jargon, so if you could explain it in simple terms, that would be greatly appreciated. Thank you in advance for your help!
