Homepage settings are located in Appearance → Customise → Homepage Settings.
Homepage Principle
Unlike many other themes, that create numerous pages in the WordPress dashboard for each homepage or demo, there’re no extra static pages created in Uppercase.
We believe that content and appearance are different things and should not be mixed together.
Instead, you may configure your homepage in one single place with live preview: in Appearance → Customise → Homepage Settings.
Homepage Layout
You may configure your homepage layout in Appearance → Customise → Homepage Settings → Homepage Layout.
Static Front Page

If you, however, select a static page for your homepage in Appearance → Customise → Homepage Settings → Static Front Page, the option Display Location will appear in the Hero Section:
This option will allow you to select the location for the section: either the homepage (the static front page), or the posts page (the blog page).
