I would recommend deleting the screenshots, though. I looked at them and thought "so what? that's been done many times before" until I read the text more carefully.
I would recommend reshooting the screenshots. Navy blue on a jet black background? Removing new lines in the initial example but not in the diffs? Fixing those would get the point across better.
Also, turn the saturation down. That’s the greenest green and the reddest red next to the darkest blue. My eyes.
