@heyodai It's a macOS-specific file. We can remove it and add it to .gitignore?

@rahulmysore23 - Per Stack Overflow, I think we need to first do this before adding it to .gitignore:

git rm -r --cached .DS_Store
git commit -m "Remove ignored files"

.gitignore only affects future commits, so it won't remove it from the git history.

I've been through this before, unfortunately 😅 This ticket is just a reminder for me to go do this at some point.
