Hi David, for some reason when I create the README file and then change/add the text and hit 'commit' again, my README file isn't there to stage. I've tried deleting the local-first project, creating a new one and starting over, and I get the same issue.
David Keyes Founder • October 21, 2021
Glad you got it figured out!
Derrick Watsala • September 16, 2025
Hi David, I am using Windows, different from yours - Mac. Does this explain why I can't see the coloring say orange for deletions, green additions made while committing?
Derrick Watsala • September 17, 2025
Hi David - I rechecked and now I know this works.
