You can create up to 5 pages with a complex content formatting similar to home page. First you need to create a simple shopify page in the admin section Online Store > Pages.
To enable page constructor for this page set "Template suffix" in the Template section on the right to page.custom1 – page.custom5. You can only have 5 pages with constructor in your shop by default. If you need more, you can create a new file in your theme like "sections/page-constructor-6.liquid" and paste the code from "sections/page-constructor-5.liquid" into it.
