Adding a description to your element will help to communicate the intent behind the element to your current and future team members.
Click on "configure content" to add a description field/box to the element overview. You can also change the order or location of the description box by dragging it into the required position.
You can now add a description for your element by in-line editing. Optionally add tables, images, and links. Remember to click on save, once you are done.
