What is the first thing to do to add a border to a paragraph?

To add a border to a paragraph, the first step is to select the paragraph you want to modify. In most Word processing software, you can then access the "Borders" or "Shading" option from the formatting toolbar or menu. From there, you can choose the style, color, and width of the border you wish to apply. Finally, apply the settings to see the border around the selected paragraph.
