The GovCMS default layout includes a logo in the header of your site. In this exercise, we’ll change this logo. If you have a logo on your computer you can use that one. If not, find a sample logo on the internet that you can use for this exercise.
Go to Appearance and click the Settings link next to the “Olivero” theme.
Unselect the “Use the logo supplied by the theme” checkbox, then use the Upload logo image button to upload the new logo.
Click Save configuration.
Now check what the logo looks like on the site. You can also go back to the theme configuration page to adjust the logo’s pixel width (the height will adjust correspondingly).
