 ### Why do I need the peer dependencies?
 
-The ESLint plugins are peer dependencies due to a limitation within ESLint. See [issue](https://github.com/eslint/eslint/issues/3458), [RFC](https://github.com/eslint/rfcs/tree/master/designs/2019-config-simplification), and [progress](https://github.com/eslint/eslint/issues/13481).
