Create New Design
Here, a design refers to a single product detail page.
To create a product detail page, click the Create New Design button.
Once you log in, you'll see the dashboard screen above.
Do you see the "Create New Design" button in the center?
Click it to start building your product detail page right away.
If you've already created designs before, you can also view and jump in to edit them from this screen.
After clicking the button, you'll see the selection screen above.
If this is your first time, click the "Start from Scratch" button.
You can then create a brand new product detail page from the ground up.
