From your WordPress dashboard, select Settings>Reading
At the top, next to “Your Homepage Displays”, select “A static page“
Under the Homepage dropdown, select your home page. If you want to display the Coming Soon Page, you can choose this page instead and then change the Homepage later when you’re finished setting up your site.
In the “Posts page” dropdown, choose the Blog Archive page. This will allow posts to be filed in the archive while preserving your custom blog page design.
