+# use-styled-react-import
+
+💼 This rule is _disabled_ in the ✅ `recommended` config.
+
+🔧 This rule is automatically fixable by the [`--fix` CLI option](https://eslint.org/docs/latest/user-guide/command-line-interface#--fix).
+
+<!-- end auto-generated rule header -->
+
+Enforce importing components that use `sx` prop from `@primer/styled-react` instead of `@primer/react`.
+
+## Rule Details
+
+This rule detects when certain Primer React components are used with the `sx` prop and ensures they are imported from the temporary `@primer/styled-react` package instead of `@primer/react`. It also moves certain types and utilities to the styled-react package.
+
+### Components that should be imported from `@primer/styled-react` when used with `sx`:
+
+- ActionList
+- ActionMenu
+- Box
+- Breadcrumbs
+- Button
+- Flash
+- FormControl
+- Heading
+- IconButton
+- Label
+- Link
+- LinkButton
+- PageLayout
+- Text
+- TextInput
+- Truncate
+- Octicon
+- Dialog
+
+### Types and utilities that should always be imported from `@primer/styled-react`:
+
+- `BoxProps` (type)
+- `SxProp` (type)
+- `BetterSystemStyleObject` (type)
+- `sx` (utility)
+
+## Examples
+
+### ❌ Incorrect
+
+```jsx
+import {Button, Link} from '@primer/react'
+
+const Component = () => <Button sx={{color: 'red'}}>Click me</Button>
+```
+
+```jsx
+import {Box} from '@primer/react'
+
+const Component = () => <Box sx={{padding: 2}}>Content</Box>
+```
+
+```jsx
+import {sx} from '@primer/react'
+```
+
+### ✅ Correct
+
+```jsx
+import {Link} from '@primer/react'
+import {Button} from '@primer/styled-react'
+
+const Component = () => <Button sx={{color: 'red'}}>Click me</Button>
+```
+
+```jsx
+import {Box} from '@primer/styled-react'
+
+const Component = () => <Box sx={{padding: 2}}>Content</Box>
+```
+
+```jsx
+import {sx} from '@primer/styled-react'
+```
+
+```jsx
+// Components without sx prop can stay in @primer/react
+import {Button} from '@primer/react'
+
+const Component = () => <Button>Click me</Button>
+```
+
+## Options
+
+This rule has no options.
+
+## When Not To Use It
+
+This rule is specifically for migrating components that use the `sx` prop to the temporary `@primer/styled-react` package. If you're not using the `sx` prop or not participating in this migration, you can disable this rule.
