Setting Static Page as The Front Page
By default, WordPress would use blog posts index as the front page. But you can use other custom static page as the home page. First, you need to create your static page, fill it with content. Or if you have used demo data impor, you could directly go to Settings > Reading.
There would be a "Front page displays" option. Set the value to "A static page", and then set the "Front page" option to your custom static home page. You would also need to set the "Posts page" option to a new custom page. This new custom page will replace the default Blog posts index page.
