Have Complete the Get Started Guide - How to Setup for Mainnet?

Dear Community,

I have completed the “Get Started” guides successfully. Right now, I would like to Create New Transaction (Value) using Mainnet.

Sorry, I’m kind of confuse when I read the next column, that is “Specs” and “Tools” - I really don’t know where to begin to setup for Mainnet because as what I may have understand that I have downloaded all those “interledgerrs” using Docker, can I use this Docker to run for Mainnet?

Also, for using Mainnet is there possible for me to have 2 separate accounts for sending and receiving?

I need guidance and I’m using MacBook Pro.
