How do I change my homepage to be a different page?

You can change which page or path on your site acts as the homepage. For example, say you wanted your blog page to become your homepage. In effect, this would mean that the content that displays on the blog page would then display on your homepage. You can do this easily by going to Settings / Site Settings in your administration menu (see image below)

Then scroll to the bottom and in the "Default Frontpage" field (see image below) enter the page you would like to be the homepage (ex. blog).
