When creating or editing a note, you can attach files by clicking the attachments "paperclip" icon

This opens a dialog where you can select one or more files to be attached to the note.

When you have attached the file(s), they show in a list above your note's text:


To remove these files, press the "Remove All" button, or select a single file and press the "Remove Selected" button.
To attach more files, click the paperclip icon again.

When your note is saved, it appears on the pinboard with a small paperclip icon in the top corner, so other members of your space can open, edit and save the attached files.
