   When you see the Details tab, you can make changes to the file, if necessary. Specifically, you can rename the file and add tags to it. You can also upload another version of the document.

7. To return to the Document Dashboard, do one of the following:
   • If you make any changes to the file, click Save.
   • If you did not make any changes to the file, click Home .
