Notes are text documents for a project. Their main function is to keep important information about the project.
Pin the project note
This will show up on the detail of the project and will be more in the eye. Typically, it is good to pin some “must know” things about the project.
Restrict access to a note
The basic note is visible to all users. However, if you want to see only a few selected, simply click on the green Plus button above the note. In the list, you select the users who want to see it and it is.
Discussions / Comments / Files at a note
You can discuss as well as you would with the tasks. You can attach files to make complex notes and background documents.
