Improve instruction

ensure consistency with earlier steps

Hey, thanks for the suggestion.

I think, in this case, the intent with the instructions as written is to indicate that the user would typically just be running git add on the individual files they've changed in each normal development cycle. So if they might create file.psd, edit it a bit, then run git add file.psd and commit, and repeat with some other file.

I'm inclined to close this PR, then, but if this particular instruction still seems problematic, perhaps we could instead add a note that this would be expected after you've created or edited file.psd.
