 ## Installation
 
-Using your favorite package manager, install:
+Install the base package (which can either be the free Community version or the paid Pro version) along with a required third-party date library.
+The Pickers currently support [Day.js](https://day.js.org/), [date-fns](https://date-fns.org/), [Luxon](https://moment.github.io/luxon/#/), and [Moment.js](https://momentjs.com/).
 
-- `@mui/x-date-pickers` for the free community version or `@mui/x-date-pickers-pro` for the commercial version.
-- The date library to manipulate the date.
+Choose your packages and manager through the toggles below, then run the commands as provided to install:

-If you need more information about the date library supported by the Date and Time Pickers,

+:::success
+Not sure which date library to choose?
+If you're starting from scratch with no other date libraries in your app, we recommend Day.js because of its small bundle size.

-### Style engine
-
-Material UI is using [Emotion](https://emotion.sh/docs/introduction) as a styling engine by default. If you want to use [`styled-components`](https://styled-components.com/) instead, run:
-
-<codeblock storageKey="package-manager">
+## Date library adapter setup
 
-```bash npm
-npm install @mui/styled-engine-sc styled-components
-```
+To integrate your chosen date library with the Date and Time Pickers, you'll need to plug the corresponding adapter into a `LocalizationProvider` that wraps your Picker components.
 
-```bash pnpm
-pnpm add @mui/styled-engine-sc styled-components
-```
+Adapters are provided for each of the supported libraries, and all are exported by both `@mui/x-date-pickers` and `@mui/x-date-pickers-pro`—for example,`AdapterDayjs`, which is used throughout this documentation for [Day.js](https://day.js.org/) integration:
 
-```bash yarn
-yarn add @mui/styled-engine-sc styled-components
+```tsx
+import { AdapterDayjs } from '@mui/x-date-pickers/AdapterDayjs';
+import { AdapterDayjs } from '@mui/x-date-pickers-pro/AdapterDayjs';
 ```
 
-</codeblock>
-
-Take a look at the [Styled engine guide](/material-ui/integrations/styled-components/) for more information about how to configure `styled-components` as the style engine.
-
-## Setup your date library adapter
+### LocalizationProvider
 
-Before trying to render any component, you have to make sure that there is a `LocalizationProvider` upper in the React tree.
-This component receives your chosen [date library's adapter](https://mui.com/x/react-date-pickers/#date-library) (the doc uses `AdapterDayjs` which is based on [dayjs](https://day.js.org/)) and makes it accessible to all the Date and Time Pickers component using React context.
+The `LocalizationProvider` component is exported by both `@mui/x-date-pickers` and `@mui/x-date-pickers-pro`:
 
-Each demonstration in the documentation has its own `LocalizationProvider` wrapper.
-This is **not** a pattern to reproduce.
-The reason is to keep examples atomic and functional, especially when running in a CodeSandbox.
+```tsx
+import { LocalizationProvider } from '@mui/x-date-pickers/LocalizationProvider';
+import { LocalizationProvider } from '@mui/x-date-pickers-pro/LocalizationProvider';
+```
 
-The general recommendation is to declare the `LocalizationProvider` once, wrapping your entire application.
-Then, you don't need to repeat the boilerplate code for every Date and Time Picker in your application.
+:::warning
+For practical purposes, each demo in the documentation has its own `LocalizationProvider` wrapper.
+**We _do not_ recommend reproducing this pattern as-is.**
+For almost all use cases, you should wrap your entire app with a single `LocalizationProvider` to avoid repeating boilerplate code in multiple places.
