Posts Page setup
If you followed the previous section then you should already have a page created to display blog posts. If it’s not already done, then create a new page on your website, with the WP Dashboard > Pages > Add New. Give the name the new page Blog, for example. Publish your page.
Next, go to WP Dashboard > Settings > Reading, and select the created page as the Posts page. Here you can set also the number of displayed posts on one page.
The Customizer allows you to customize view of post list when a Posts Page (blog home or archives) is show or when a single post is displaing. To make it go to the panel called Posts Page and/or Single Post.
