Getting started with GSplus

[Gitme2024-prog]

Hello there fellow apple iigs enthusiasts! I have downloaded the gsplus files and started it up, but I'm unsure what to do next. I'm a luddite and could use some help. I have put the rom1 and rom 3 in the folder. It brings me to the two screens, one showing code on the left, and the other showing the iigs blue screen on the right, with an asterisk and a cursor waiting for me to type something. Help!
