@sql-sith - unfortunately, this was a long time back, so I don't remember all the details.

I had a situation where the install-sql-modules.ps1 script was being re-run, and it was problematic the 2nd time if the cert was already there. This patch simply checks if it's there, and if not, creates it, otherwise it skips it.

As for the branching/dev/etc., I followed this guide: https://aws-quickstart.github.io/option2.html

HTH!
