New to hacking. Need advice

Hello, i'm new to the world of rom hacking/editing, and would love to edit and make my own game built upon FF6.

I have no programing knowledge, so I don't plan on changing code, but i'd like to use an existing rom editor to get my idea off the ground.

So i'm thinking about using Final Fantasy 3 us Multi Editor, i've played around with it in the past, but i've had trouble figuring out, where to start, ect.

I was wondering if anyone had any guides/walkthroughs on getting started using this program, and how to get stuff going? I've searched google to no avail.

If anyone has any advice on other programs, or starting a project in general, I would appreciate it greatly. Thank you!
