Your Home Page is the first page that people see when they land on your site at http://www.yoursitename.com
It is important that you customize it to represent your brand in the best way possible, and entice people to stay and look at the rest of your content.
Your Home Page can be set up to either show several posts and site features, like the default blog template you get, or you can change it to show just one page for example your About page or maybe a Welcome Note from you.
If you’d like to do that, simply navigate to Dashboard > Settings > Reading and choose Front page displays a Static Page, then select the page you’d like to have on your Home Page, as well as the one for all your latest blog posts accordingly.
Please note that you can only do this with a page, not a post.
