 💼 This rule is enabled in the following [configs](https://github.com/jsx-eslint/eslint-plugin-react#shareable-configurations): `all`.
 
+🔧 This rule is automatically fixable using the `--fix` [flag](https://eslint.org/docs/latest/user-guide/command-line-interface#--fix) on the command line.
+
 Some developers prefer to sort prop type declarations alphabetically to be able to find necessary declaration easier at the later time. Others feel that it adds complexity and becomes burden to maintain.
