## What docs page needs to be fixed? Page: https://redux.js.org/usage/structuring-reducers/normalizing-state-shape This page is referenced in the [Redux Style Guide](https://redux.js.org/style-guide/). ## What is the problem? At the end of the article, the library Normalizr is suggested for normalizing nested data into a normalized format. Normalizr is [no longer maintained as of March 19, 2022](https://github.com/paularmstrong/normalizr/discussions/493#discussioncomment-2395540). ## What should be changed to fix the problem? The article should describe a more modern solution to normalizing nested data, such as Redux Toolkit's `createEntityAdapter`.
