 ### Development flag
 The three settings for result cache, schema cache and field security have been replaced with one `development` flag, which turns the GraphQL module into development mode. This will also enable advanced error reporting in the underlying execution library.
 
+Before:
+```yaml
+parameters:
+  graphql.config:
+    # GraphQL result cache:
+    #
+    # By default, the GraphQL results get cached. This can be disabled during development.
+    #
+    # @default true
+    result_cache: true
+
+    # GraphQL schema cache:
+    #
+    # By default, the GraphQL schema gets cached. This can be disabled during development.
+    #
+    # @default true
+    schema_cache: true
+
+    # Development mode:
+    #
+    # Disables field security. All fields can be resolved without restrictions.
+    #
+    # @default false
+    development: false
+```
+
+After:
+```yaml
+parameters:
+  graphql.config:
+    # Development mode:
+    #
+    # Enables debugging mode and disables field security and caching.
+    #
+    # When enabled, all fields can be resolved without restrictions
+    # and the caching strategy of the schema and query results is
+    # disabled entirely.

 ### Enum definitions
 `buildEnumValues` has to return an array of the following structure:
 
 ```php
 [

-	  'value' => 'a',
