My friend has shared a file with me on Google Drive and I would like to be notified whenever changes are made to the file (pretty reasonable request I'd say):You can set notifications to find out when your  collaborators have modified your spreadsheets, and learn what sheets  or cells they've modified. You can also choose how often you'd like to  be notified. Here's how you can enable notifications:Click Share at the top right of the spreadsheet and select Set  Notification Rules. In the window that appears, select when and how  often you want to receive notifications: a. When changes are made to the  entire spreadsheet b. When changes are made to a specific sheet c. When  changes are made to specific cells d. When collaborators are added or  removed e. When changes are made to forms f. By 'daily digest' or 'right  away' Click Save.(Source)I've tried to follow the steps but I'm stuck on step 2.. for example, when I hit share I'd get this screen:How do we set up notifications for documents shared to us in Google Docs?
How do we set up notifications for documents shared to us in Google Docs?

@Pacerier's answer is correct  for a spreadsheet. For a word processing document or presentation, that menu does not exist.As far as I have found, word processing and presentation documents provide notifications for updates to comments, but not the content of the document. Comment notifications seem to be enabled by default and can be changed by clicking the Comments button (next to the Share button, in the top right area of the page) and then Notification Settings.
