I ran it, I have a project, and I ran rails c and rails s with the expected results.

However, the end of the log exited with a non-zero exit code? Not sure what's going on there.

# ... log log log ...
create mode 100644 zap.conf
         run  git add . from "."
         run  git commit -a -m 'Initial commit' from "."
On branch main
nothing to commit, working tree clean
⚠️   1   # <-- the non-zero exit

Otherwise, just left a couple suggested changes for the readme.

change (non-blocking): Even though I think I was the person who wrote the readme, I was confused trying to follow it! The commands are nested inside numbers, then bullets, then sub-bullets, then parentheses. I

change: It asked me about docker-trestle and compliance-as-code and I had no idea what to select and the readme doesn't explain it. Could you add something about that to guide a decision?

I'm 99% certain that's from the git commit resulting in "nothing to commit, working tree clean". Which is itself surprising, unless you ran it multiple times with the same destination directory?

EDIT: Yep, that's it!

I don't love ADDITIONAL_CONFIG_OPTIONS but couldn't think of a better way to say "insert any --no-skip... options here"
