How to Add a Header to Page One
Download LibreOffice free of charge from the official website, and follow these steps to add a first-page header:
Open a LibreOffice text document and place the cursor on the first page. In the menu bar, click Format and select Styles and Formatting from the drop-down menu. Or, press the F11 keyboard shortcut. In the Styles and Formatting pop-up box, select the Page Styles icon and choose First Page. In the menu bar, select Insert > Header > First Page. Your document is now set up to have a different header on the first page, so go ahead and add your information, knowing that this header will be unique.
