 ### Language Config
 
-The configuration file used to control the Language Features and Language Servers.
-
-Language Features and Language Servers are typically used by IDEs and editors to provide language features such as hover information, auto completion, jump to definition, error checking, formatting, refactoring, and more.
+The configuration file specifies the root files and the options for the features provided by the language service.
 
 ESLint React uses the Language Config to provide information (e.g. [JSX Transform](/docs/configuration/configure-language-config#jsx-transform)) about the code it is linting.
