@macmanx With the Lodestar theme, as far as I can tell, you can’t manually edit the first page users see when the site loads, as that is not a “page” in this theme.
The page labeled “Home” in this theme is actually the page that users see once they start scrolling. On my site, it is the page with my site’s logo that reads, “Resources for teachers who are seeking to build wealth through doing what they love – teaching!”
In Lodestar, the first page users see seems to purely be generated by what you type into the theme’s customizer under “site identity” – the Site Title + the Site Tagline.
