+
+## What is this?
+
+This package is a *context* based components provider for combining React with
+MDX.
+
+## When should I use this?
+
+This package is **not needed** for MDX to work with React.
+See [¶ MDX provider in § Using MDX][use-provider] for when and how to use an MDX
+provider.
+
+If you use Next.js, **do not use this**.
+Add an `mdx-components.tsx` (in `src/` or `/`) file instead.
+See [Configuring MDX on `nextjs.org`][next-configuring-mdx] for more info.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 16+), install with [npm][]:
+
 ```sh
-npm install --save @mdx-js/react
+npm install @mdx-js/react
 ```
 
-## Usage
+In Deno with [`esm.sh`][esmsh]:
 
-```md
-<!-- helloworld.md -->
+```tsx
+import {MDXProvider} from 'https://esm.sh/@mdx-js/react@2'
+```
 
-# Hello, World!
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+<script type="module">
+  import {MDXProvider} from 'https://esm.sh/@mdx-js/react@2?bundle'
+</script>
 ```
 
-```jsx
-import React from 'react'
+## Use
+
+```tsx
 import {MDXProvider} from '@mdx-js/react'
-import {renderToString} from 'react-dom/server'
+import Post from './post.mdx'
+// ^-- Assumes an integration is used to compile MDX to JS, such as
+// `@mdx-js/esbuild`, `@mdx-js/loader`, `@mdx-js/node-loader`, or
+// `@mdx-js/rollup`, and that it is configured with
+// `options.providerImportSource: '@mdx-js/react'`.
 
-import HelloWorld from './helloworld.md'
+/** @type {import('mdx/types.js').MDXComponents} */
+const components = {
+  em(props) {
+    return <i {...props} />
+  }
+}
 
-const H1 = props => <h1 style={{color: 'tomato'}} {...props} />
-
 console.log(
-  renderToString(
-    <MDXProvider components={{h1: H1}}>
-      <HelloWorld />
-    </MDXProvider>
-  )
+  <MDXProvider components={components}>
+    <Post />
+  </MDXProvider>
 )
 ```
 
-Yields:
+> 👉 **Note**: you don’t have to use `MDXProvider` and can pass components
+> directly:
+>
+> ```diff
+> -<MDXProvider components={components}>
+> -  <Post />
+> -</MDXProvider>
+> +<Post components={components} />
+> ```
 
-```html
-<h1 style="color:tomato">Hello, world!</h1>
-```
+See [¶ React in § Getting started][start-react] for how to get started with MDX
+and React.
+See [¶ MDX provider in § Using MDX][use-provider] for how to use an MDX
+provider.
 
+## API
+
+This package exports the identifiers [`MDXProvider`][api-mdx-provider] and
+[`useMDXComponents`][api-use-mdx-components].
+There is no default export.
+
+### `MDXProvider(props?)`
+
+Provider for MDX context.
+
+###### Parameters
+
+* `props` ([`Props`][api-props])
+  — configuration
+
+##### Returns
+
+Element (`JSX.Element`).
+
+### `useMDXComponents(components?)`
+
+Get current components from the MDX Context.
+
+###### Parameters
+
+* `components` ([`MDXComponents` from `mdx/types.js`][mdx-types-components]
+  or [`MergeComponents`][api-merge-components], optional)
+  — additional components to use or a function that creates them
+
+###### Returns
+
+Current components ([`MDXComponents` from
+`mdx/types.js`][mdx-types-components]).
+
+### `MergeComponents`
+
+Custom merge function (TypeScript type).
+
+###### Parameters
+
+* `components` ([`MDXComponents` from `mdx/types.js`][mdx-types-components])
+  — current components from the context
+
+###### Returns
+
+Additional components ([`MDXComponents` from
+`mdx/types.js`][mdx-types-components]).
+
+### `Props`
+
+Configuration for `MDXProvider` (TypeScript type).
+
+###### Fields
+
+* `children` ([`ReactNode` from `react`][react-node],
+  optional)
+  — children
+* `components` ([`MDXComponents` from `mdx/types.js`][mdx-types-components]
+  or [`MergeComponents`][api-merge-components], optional)
+  — additional components to use or a function that creates them
+* `disableParentContext` (`boolean`, default: `false`)
+  — turn off outer component context
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It exports the additional types [`MergeComponents`][api-merge-components] and
+[`Props`][api-props].
+
+For types to work, make sure the TypeScript `JSX` namespace is typed.
+This is done by installing and using the types of your framework, as in
+[`@types/react`](https://github.com/DefinitelyTyped/DefinitelyTyped/tree/HEAD/types/react).
+
+## Compatibility
+
+Projects maintained by the unified collective are compatible with maintained
+versions of Node.js.
+
+When we cut a new major release, we drop support for unmaintained versions of
+Node.
+This means we try to keep the current release line, `@mdx-js/react@^3`,
+compatible with Node.js 16.
+
+## Security
+
+See [§ Security][security] on our website for information.
