This theme uses the WooCommerce plugin, which can be obtained here or by searching in Dashboard > Plugins > Add New. You will also need to install the Genesis Connect for WooCommerce plugin, which can be obtained here or by searching in Dashboard > Plugins > Add New.
Once installed WooCommerce will walk you true the basic setup of your web shop. WooCommerce will add in these steps the most importent pages and end-points e.g. the cart, checkout, account etc.
Next step is to create a shop page. Navigate to Pages > Add New. Create a new page with the name shop or any other name. Save the page. Next navigate to WooCommerce > Settings > Products > Display. Under Shop & Product Pages set the shop page to the page you’ve just created.
Stay on the same page and check the Product images settings. Configure as you see below:
Don’t forget to save the changes.
PLEASE NOTE: While this theme is pre-styled to work with WooCommerce, I offer no support for the plugin itself beyond the installation instructions since it wasn’t developed by me. Should you need further support for WooCommerce please visit here.
