There are two ways to edit a Project's information in the Portfolio editor.
The first way is to click on the pencil icon that appears on the desired Project's cover image. Select "Edit Info" from the dropdown menu that appears and you will be able to edit your Project's Title, Description, Creative Fields, and more.
The other way is to navigate to the Project page and select "Edit Info" from the editing remote.
To select which pieces of info you want displayed on your Project covers, select Project Covers from the Gallery remote. You can then toggle info on or off.
