This article was super helpful!
I managed to set two Glitch projects to behave like my development and production environments, with my main repo being in GitHub and everything working CI/CD style. Thank you very much!

I have three comments:

• I'd clarify that the GitHub action uses somebody else's code from github.com/wei/git-sync
• The GitHub repo should be public. Otherwise you need to also set a SSH public key as explained in the link above.
• Minor: In the article you say "Replace YOUR GITHUB REPO URL HERE with your https GitHub URL", but there is no "YOUR GITHUB REPO URL HERE" in the action code (although the solution is obvious :)

Cheers!
