You can use notes to add reminders or development notes. A note can remind you of further development that needs to be done.
To add a note, complete the following steps:
at the top of the palette and click again on the canvas to
place the note.
and then click the note and then an artifact. The note is now associated with that artifact. That association is
maintained if you use refactoring to rename or move the artifact.
If you check the artifact into a repository, the note will travel
with it.
