Configuring Serenity’s one-page template is super easy and takes less than 1 minute.
Start by creating (or editing) a page.
Give it a title of Home and assign it the One-page Template under the Page Attributes section. You will want to create a 2nd page (without any content) titled Blog to display your blog posts.
Go to Settings > Reading.
Set Front page displays to A static page. Then from the drop-down, select the Home & Blog pages you just created.
Then click Save Changes at the bottom.
That’s it, you’re done!
