@tatarincev, i made a commit 1e1c422 to branch with scriban theme and also made a comment VirtoCommerce/vc-storefront#188 (comment) about syntax change,but still have few problems here:

1. Can't show "Sign in/Create an account" links. I guess it's because of property "shop.customer_accounts_enabled", but i can't find it
   

   vc-theme-default/layout/account_layout.liquid

   Line 80 in 1e1c422

   {% if settings.header_message != blank or shop.customer_accounts_enabled %}

2. Same as 1)
   

   vc-theme-default/layout/theme.liquid

   Line 90 in 1e1c422

   {% if settings.header_message != blank or shop.customer_accounts_enabled %}

3. It shows an error that something wrong with "For" loop.
   
   

   vc-theme-default/templates/list-collections.liquid

   Line 6 in 1e1c422

   {% for link in linklists.all-collections.links %}

4. allVariationPropsMap is a variable from assets/js/product.js, but function getFlatternDistinctPropertiesMap returns empty object when i debug it. I think it can be something with dependency script locally,because in old version of theme i have the same result without showing props.
   

   vc-theme-default/templates/product.liquid

   Line 119 in 1e1c422

   <div ng-repeat="(propName, props) in allVariationPropsMap">

   
   

   vc-theme-default/assets/js/product.js

   Line 75 in 1e1c422

   $scope.allVariationPropsMap = getFlatternDistinctPropertiesMap(allVariations);

5. "For" loop is not working.
   

   vc-theme-default/snippets/collection-sidebar.liquid

   Line 4 in 1e1c422

   {% for cat_item in collection.all_tags.groups %}

6. Images and prices for products are not showing
   

   vc-theme-default/snippets/product-list-item.liquid

   Line 29 in 1e1c422

   <img src="{{ product.featured_image.src | img_url }}" alt="{{ product.featured_image.alt | escape }}" />
