While your logbook entries themselves provide a lot of detail including time, date, location and vehicle driven it can be beneficial to add a comment with more detail important to that shift.
You can add a comment to your work shift either:
While you are still in the middle of your work day
While reviewing your shift prior to locking.
Regardless of when you are adding the comment it is done in the same way.
Click on either the logbook icon in the bottom navigation bar or the "review & lock" button
Click on the pencil next to the comment section
Type in your comment and click Save
