Shopify themes usually comes with around 15 sections for you to design your store. If you don't like those sections or need something extra you are stuck with hard to learn page-builder apps, or expensive developers. Section Store is solving that issue with a section library full of plug-an-play customisable sections, that you can simply add to any theme on your store and customise in the theme editor. Think features, testimonials, faq, trust badges etc.
