Create two new pages in WordPress (under Pages > Add new), and publish them.
For the purpose of example, we’ll call these “Welcome” (for the front, or Home, page) and “Blog”.
Go to Settings > Reading Settings, and under “Front page displays”, click the radio button for
A static page.
Select “Welcome” in the first drop down (for
Front page), and select “Blog” in the second one (for
Posts page). Save the changes.
