 ## Rules that Need Type Information
 
+ESLint React uses the Typed Linting API from `typescript-eslint` to retrieve type information for the rules that require it. The `project` or `projectService` options in `parserOptions` must be set correctly for the rules to work.
+
 The following rules require type information:
 
 - [`react-x/prefer-read-only-props`](/docs/rules/prefer-read-only-props)
 - [`react-x/no-leaked-conditional-rendering`](/docs/rules/no-leaked-conditional-rendering)
 
-These rules will not work if you do not provide a `project` or `projectService` in the `parserOptions`.
-
-This part has a performance impact, as it requires TypeScript to analyze the entire project. As a result, these rules are slower than traditional lint rules but are much more powerful.
+Enabling these rules can impact performance because it requires TypeScript to analyze the entire project. Therefore, these rules run slower than traditional lint rules, but they are also more powerful in functionality.
