After installed the theme, I still know nothing about managing and running the website, like where to start upload the products, where to edit the content. I totally have no clue about all the stuff, this’s killing me. Please if anyone can help me with this!
Thank you for choosing our theme for your project.
We are not responsible for Envato service and you have to contact Envato team if you have any questions regarding their services.
As for the site managment, we suggest you to start learning from WordPress documentation, then WooCommerce and WPBakery page builder. Of course, you will need to read our theme documentation as well https://xtemos.com/documentation/woodmart/
Each submenu for the category is HTML template. So, first of all, create the block for each category https://xtemos.com/docs/woodmart/html-blocks-2/ If you add new, or try editing an existing one, you will see that HTML block is WP bakery template.
