Your website's Site Info widget can be edited right on your front page. It contains information such as title, description and address. You can edit this information by hovering over the site information on your home page and clicking the grey gear button that appears to the far right, select "Edit Widget".
The "Site Title" field is usually reserved for your name on a personal site, or the department name on a department site.
The "Description" is normally for your professional title on a personal site, or additional information on a department site.
The "Address" line is your office address (for personal sites). For department sites, this information typically goes in a footer.
This information will automatically appear in your site's header section. Both "Description" and "Address" are optional fields. Remember to save.
