I find it very difficult to get started

Here is my link : Webflow - Life Digital Planner

I purchased a theme and now trying to build an e-commerce store for a digital product. The site will include basic pages: landing page, contact, product, FAQ, and login dashboard for downloading the purchase, online courses page for paid members.

I am struggling to get started with the template. How to make the intro page (i.e. the main page when customers land to the site), how to add eCommerce functions (i.e. product page and checkout), payment integration, login … etc.

I have basic experience in CSS, clickfunnels, shopify, wordpress …etc but I am struggling here to understand. I’ve watches a number of videos, but they seems to be outdated and not aligned with current dashboard.

I look for your support please.
