The Blog page
Let’s set the Blog Page. First step is to create a New Page. Go to Pages > Add new and create a New page. Give it a name e.g. “Blog” or “Blog Entries”. Hit the Publish button on the top right.
Next step is to assign this page as the page that displays the posts. Go to Settings > Reading and from the first set of radio buttons, check the “A Static page” and from the Posts Page dropdown select the page you have created, like at the screenshot below. Do not worry about the Front Page dropdown for now, we will work on this later. Click Save and you are good to go.
Setting the "Read More" link at blog posts
At the blog page, you will see that each post has a short description under it, and there is a Continue Reading link that leads you to the full post page. In order to define this “breakpoint” you must use the Insert More Tag button which is located at the text editor, as highlighted at the screenshot below.
Place the cursor to the point of the content where you wish to show the Continue Reading link, and click on the button shown at the above screenshot.
