By default, the theme will show your site title and site tagline. However, to really bring your brand into the theme, you can upload your own brand logo.
To do this, open up the Site Identity section.
At the top of this section, you will see the logo section. Click Select logo and then either upload a new image or choose one from your media library.
After selecting an image you will be given the option to crop your logo. If you don’t want to crop your logo, click Skip Cropping.
You should now be able to see your logo on your website instead of the site title and tagline.
Uploading a logo will automatically remove the site title and tagline that is displayed by default.
