The first thing you’ll need to do is create two new pages: One called Home (or Portfolio) and one called Blog.
Then, look in the Page Attributes section of your Home/Portfolio page and select the Portfolio Page template.
Now you can open the Customizer and go into the Homepage Settings panel.
Select “A static page” for your homepage, and choose “Home (Portfolio)” for the static homepage, and “Blog” for your blog page.
At this point you should see your portfolio projects on your homepage.
The next step will be to go into your Customizer’s Menus section and add your new Blog page to your menu, so people will be able to find it, since it’s no longer on the front page.
Hope that helps.
