// Add cart-drawer.liquid file within your theme's "Sections" folder
// Add ajaxify-cart.liquid file within your theme's "Snippets" folder
// Add v-drawer.css file within your theme's "Assets" folder
// Add v-drawer.js file within your theme's "Assets" folder
After all files have been uploaded, in your theme.liquid main file, right under the <body> element, add the following line of code:
{% section 'cart-drawer' %}
Now, find the element which when clicked will open the drawer cart (the cart icon from the header, as an example). Find his unique class, then go v-drawer.js line 3 and add it there
Enjoy!
