 ### Settings
 
 The module provides a common `settings` method to customize various features.
 
-Before version 7.0.0 of the gem, the only supported setting was `:inheritance_enabled`. This setting has been deprecated
-and removed.
+At the moment, the only supported setting is `:inheritance_enabled`, which makes the class receiving the module
+respect index names and document types of a super-class, eg. in case you're using "single table inheritance" (STI)
+in Rails:
 
+```ruby
+Elasticsearch::Model.settings[:inheritance_enabled] = true
+```
+
 ## Development and Community
 
 For local development, clone the repository and run `bundle install`. See `rake -T` for a list of
 available Rake tasks for running tests, generating documentation, starting a testing cluster, etc.

-### Single Table Inheritance deprecation
-
-`Single Table Inheritance` has been supported through the 6.x series of this gem. With this feature,
-elasticsearch settings (index mappings, etc) on a parent model could be inherited by a child model leading to different 
-model documents being indexed into the same Elasticsearch index. This feature depended on the ability to set a `type` 
-for a document in Elasticsearch. The Elasticsearch team has deprecated support for `types`, as is described 
-[here.](https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html)
-This gem will also remove support for types and `Single Table Inheritance` in version 7.0 as it enables an anti-pattern. 
-Please save different model documents in separate indices. If you want to use STI, you can include an artificial 
-`type` field manually in each document and use it in other operations.
