TUTOS notes are small pieces of text that can be attached to nearly all Objects in TUTOS.
Whenever looking on a detail page of a TUTOS object you will see a link called "Add Note" on the navigation menu. Selecting this link will open a page where you can enter the note and a short headline which should describe the content of the new note.
This article will give you the hints how to install, maintain and customize the notes module.
Notes are enabled by default and will not require additional steps.
