-## Introduction
-
 Modules such as Config Split want to modify the configuration when it is
 synchronized between the database and the exported yaml files.
 This module provides the API to do so but does not influence a sites operation.

 ## How it works
 
-Unlike Config Filter 1.x which swaps the `config.storage.sync` service from Drupal 8 core,
-Config Filter 2.x applies the filters when the new Drupal core config storage transformation api is used.
-This means that modules that previously used Config Filter now work with the new api.
+Config Filter 1.x swaps the `config.storage.sync` service from Drupal 8 core.
+Config Filter 2.x applies the filters when the config storage transformation api is used.
+This means that modules which use Config Filter work with the API added to Drupal 8.8.
 Modules depending on Config Filter can depend on both 1.x or 2.x as the Config Filter API is the same.

 ## What is a ConfigFilter
 
+The API config filter provides has been superseeded by the config transformation
+API in Drupal core, added in Drupal 8.8. Modules should transition to the core API.

+## Requirements
+
+This module requires no modules outside of Drupal core.

+
+## Installation
+
+You probably do not need to install Config Filter.
+Install as you would normally install a contributed Drupal module. For further

+[Installing Drupal Modules](https://www.drupal.org/docs/extending-drupal/installing-drupal-modules).
