+DESCRIPTION:
+This module provide integration with Varnish reverse 
+proxy server for Drupal 8. 
+Main feature of this module is 
+providing support of varnish 
+caching for authenticated users.
+
+MAIN FEATURES:
+Varnish support out of the box.
+All you need is to install this 
+module use default.vcl from 
+this module and fill connection 
+settings for varnish terminal.
+
+Cache for anonymous users.
+Just set desired TTL in varnish 
+settings and it will works, 
+cache invalidation will happens 
+automatically and depends on new 
+Drupal 8 cache system with tags support.
+
+Cache for authenticated users.
+The same as for anonymous users 
+just fill the TTL and Varnish will 
+start to cache pages for authenticated 
+users based on PER ROLE option. We all 
+knows that page for authenticated 
+users can contain user-specific 
+content and we care about this. For 
+each user-specific block you can 
+choose to use ESI cache on PER-ROLE 
+or PER-USER basis so each user will 
+get proper content on the page.
+
+Per Entity Cache settings.
+You can select TTL on per entity (bundle) 
+settings. This module supports basic 
+entity types out of the box (node and 
+taxonomy terms) but you can easily add 
+support for any custom entity type all 
+you need is to create small plugin and 
+we will care of all other things for you.
+
+Cache invalidation.
+We use tags to control each page state, 
+so if any entity which presents on page 
+would be changed in Drupal, cache in 
+Varnish would be invalidate immediately. 
+Module support Drupal 8 cache system and 
+use all available cache metadata so you can 
+easy add required tags for any page that you want.
