+## What is this?
+
+This package is a utility that takes a [hast][github-hast] tree and an
+[automatic JSX runtime][reactjs-jsx-runtime] and turns the tree into anything
+you wish.
+
+## When should I use this?
+
+You can use this package when you have a hast syntax tree and want to use it
+with whatever framework.
+
+This package uses an automatic JSX runtime,
+which is a sort of lingua franca for frameworks to support JSX.
+
+Notably,
+automatic runtimes have support for passing extra information in development,
+and have guaranteed support for fragments.
+
+## Install
+
+This package is [ESM only][github-gist-esm].
+In Node.js (version 16+),
+install with [npm][npmjs-install]:
+
+```sh
+npm install hast-util-to-jsx-runtime
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {toJsxRuntime} from 'https://esm.sh/hast-util-to-jsx-runtime@2'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+<script type="module">
+  import {toJsxRuntime} from 'https://esm.sh/hast-util-to-jsx-runtime@2?bundle'
+</script>
+```
+
+## Use
+
+```js
+import {h} from 'hastscript'
+import {toJsxRuntime} from 'hast-util-to-jsx-runtime'
+import {Fragment, jsxs, jsx} from 'react/jsx-runtime'
+import {renderToStaticMarkup} from 'react-dom/server'
+
+const tree = h('h1', 'Hello, world!')
+
+const doc = renderToStaticMarkup(toJsxRuntime(tree, {Fragment, jsxs, jsx}))
+
+console.log(doc)
+```
+
+Yields:
+
+```html
+<h1>Hello, world!</h1>
+```
+
+> **Note**:
+> to add better type support,
+> register a global JSX namespace:
+>
+> ```ts
+> import type {JSX as Jsx} from 'react/jsx-runtime'
+>
+> declare global {
+>   namespace JSX {
+>     type ElementClass = Jsx.ElementClass
+>     type Element = Jsx.Element
+>     type IntrinsicElements = Jsx.IntrinsicElements
+>   }
+> }
+> ```

+
+### `toJsxRuntime(tree, options)`
+
+Transform a hast tree to
+preact, react, solid, svelte, vue, etcetera,
+with an automatic JSX runtime.
+
+##### Parameters
+
+* `tree`
+  ([`Node`][github-hast-nodes])
+  — tree to transform
+* `options`
+  ([`Options`][api-options], required)
+  — configuration
+
+##### Returns
+
+Result from your configured JSX runtime
+(`JSX.Element` if defined,
+otherwise `unknown` which you can cast yourself).
+
+### `Components`
+
+Possible components to use (TypeScript type).
+
+Each key is a tag name typed in `JSX.IntrinsicElements`,
+if defined.
+Each value is either a different tag name
+or a component accepting the corresponding props
+(and an optional `node` prop if `passNode` is on).
+
+You can access props at `JSX.IntrinsicElements`.
+For example,
+to find props for `a`,
+use `JSX.IntrinsicElements['a']`.
+
+###### Type
+
+```ts
+import type {Element} from 'hast'
+
+type ExtraProps = {node?: Element | undefined}
+
+type Components = {
+  [TagName in keyof JSX.IntrinsicElements]:
+    | Component<JSX.IntrinsicElements[TagName] & ExtraProps>
+    | keyof JSX.IntrinsicElements
+}
+
+type Component<ComponentProps> =
+  // Class component:
+  | (new (props: ComponentProps) => JSX.ElementClass)
+  // Function component:
+  | ((props: ComponentProps) => JSX.Element | string | null | undefined)
+```
+

+(TypeScript type).
+
+###### Parameters
+
+There are no parameters.
+
+###### Returns
+
+Evaluater ([`Evaluater`][api-evaluater]).
+
+### `ElementAttributeNameCase`
+
+Casing to use for attribute names (TypeScript type).
+
+HTML casing is for example
+`class`, `stroke-linecap`, `xml:lang`.
+React casing is for example
+`className`, `strokeLinecap`, `xmlLang`.
+
+###### Type

+
+## Errors
+
+The following errors are thrown:
+
+###### ``Expected `Fragment` in options``
+
+This error is thrown when either `options` is not passed at all or
+when `options.Fragment` is `undefined`.
+
+The automatic JSX runtime needs a symbol for a fragment to work.
+
+To solve the error,
+make sure you are passing the correct fragment symbol from your framework.
+
+###### `` Expected `jsxDEV` in options when `development: true` ``
+
+This error is thrown when `options.development` is turned on (`true`),
+but when `options.jsxDEV` is not a function.
+
+The automatic JSX runtime,
+in development,
+needs this function.
+
+To solve the error,
+make sure you are importing the correct runtime functions
+(for example, `'react/jsx-dev-runtime'`),
+and pass `jsxDEV`.
+
+###### ``Expected `jsx` in production options``
+
+###### ``Expected `jsxs` in production options``
+
+These errors are thrown when `options.development` is *not* turned on
+(`false` or not defined),
+and when `options.jsx` or `options.jsxs` are not functions.
+
+The automatic JSX runtime,
+in production,
+needs these functions.
+
+To solve the error,
+make sure you are importing the correct runtime functions
+(for example, `'react/jsx-runtime'`),
+and pass `jsx` and `jsxs`.
+
+###### `` Cannot handle MDX estrees without `createEvaluater` ``
+
+This error is thrown when MDX nodes are passed that represent JavaScript
+programs or expressions.
+
+Supporting JavaScript can be unsafe and requires a different project.
+To support JavaScript,
+pass a `createEvaluater` function in `options`.
+
+###### ``Cannot parse `style` attribute``
+
+This error is thrown when a `style` attribute is found on an element,
+which cannot be parsed as CSS.
+
+Most frameworks don’t accept `style` as a string,
+so we need to parse it as CSS,
+and pass it as an object.
+But when broken CSS is used,
+such as `style="color:red; /*"`,
+we crash.
+
+To solve the error,
+make sure authors write valid CSS.
+Alternatively,
+pass `options.ignoreInvalidStyle: true` to swallow these errors.
+
+## Examples
+
+### Example: Preact
+
+> 👉 **Note**:
+> you must set `elementAttributeNameCase: 'html'` for preact.
+
+In Node.js,
+do:
+
+```js
+import {h} from 'hastscript'
+import {toJsxRuntime} from 'hast-util-to-jsx-runtime'
+import {Fragment, jsx, jsxs} from 'preact/jsx-runtime'
+import {render} from 'preact-render-to-string'
+
+const result = render(
+  toJsxRuntime(h('h1', 'hi!'), {
+    Fragment,
+    jsx,
+    jsxs,
+    elementAttributeNameCase: 'html'
+  })
+)
+
+console.log(result)
+```
+
+Yields:
+
+```html
+<h1>hi!</h1>
+```
+
+In a browser,
+do:
+
+```js
+import {h} from 'https://esm.sh/hastscript@9'
+import {toJsxRuntime} from 'https://esm.sh/hast-util-to-jsx-runtime@2'
+import {Fragment, jsx, jsxs} from 'https://esm.sh/preact@10/jsx-runtime'
+import {render} from 'https://esm.sh/preact@10'
+
+render(
+  toJsxRuntime(h('h1', 'hi!'), {
+    Fragment,
+    jsx,
+    jsxs,
+    elementAttributeNameCase: 'html'
+  }),
+  document.getElementById('root')
+)
+```
+
+To add better type support,
+register a global JSX namespace:
+
+```ts
+import type {JSX as Jsx} from 'preact/jsx-runtime'
+
+declare global {
+  namespace JSX {
+    type ElementClass = Jsx.ElementClass
+    type Element = Jsx.Element
+    type IntrinsicElements = Jsx.IntrinsicElements
+  }
+}
+```
+
+### Example: Solid
+
+> 👉 **Note**:
+> you must set `elementAttributeNameCase: 'html'` and
+> `stylePropertyNameCase: 'css'` for Solid.
+
+In Node.js,
+do:
+
+```js
+import {h} from 'hastscript'
+import {toJsxRuntime} from 'hast-util-to-jsx-runtime'
+import {Fragment, jsx, jsxs} from 'solid-jsx/jsx-runtime'
+
+console.log(
+  toJsxRuntime(h('h1', 'hi!'), {
+    Fragment,
+    jsx,
+    jsxs,
+    elementAttributeNameCase: 'html',
+    stylePropertyNameCase: 'css'
+  }).t
+)
+```
+
+Yields:
+
+```html
+<h1 >hi!</h1>
+```
+
+In a browser,
+do:
+
+```js
+import {h} from 'https://esm.sh/hastscript@9'
+import {toJsxRuntime} from 'https://esm.sh/hast-util-to-jsx-runtime@2'
+import {Fragment, jsx, jsxs} from 'https://esm.sh/solid-js@1/h/jsx-runtime'
+import {render} from 'https://esm.sh/solid-js@1/web'
+
+render(Component, document.getElementById('root'))
+
+function Component() {
+  return toJsxRuntime(h('h1', 'hi!'), {
+    Fragment,
+    jsx,
+    jsxs,
+    elementAttributeNameCase: 'html',
+    stylePropertyNameCase: 'css'
+  })
+}
+```
+
+To add better type support,
+register a global JSX namespace:
+
+```ts
+import type {JSX as Jsx} from 'solid-js/jsx-runtime'
+
+declare global {
+  namespace JSX {
+    type ElementClass = Jsx.ElementClass
+    type Element = Jsx.Element
+    type IntrinsicElements = Jsx.IntrinsicElements
+  }
+}
+```
+
+### Example: Svelte
+
+<!-- To do: improve svelte when it fixes a bunch of bugs. -->
+
+I have no clue how to render a Svelte component in Node,
+but you can get that component with:
+
+```js
+import {h} from 'hastscript'
+import {toJsxRuntime} from 'hast-util-to-jsx-runtime'
+import {Fragment, jsx, jsxs} from 'svelte-jsx'
+
+const svelteComponent = toJsxRuntime(h('h1', 'hi!'), {Fragment, jsx, jsxs})
+
+console.log(svelteComponent)
+```
+
+Yields:
+
+```text
+[class Component extends SvelteComponent]
+```
+
+Types for Svelte are broken.
+Raise it with Svelte.
+
+### Example: Vue
+
+> 👉 **Note**:
+> you must set `elementAttributeNameCase: 'html'` for Vue.
+
+In Node.js,
+do:
+
+```js
+import serverRenderer from '@vue/server-renderer'
+import {h} from 'hastscript'
+import {toJsxRuntime} from 'hast-util-to-jsx-runtime'
+import {Fragment, jsx, jsxs} from 'vue/jsx-runtime' // Available since `vue@3.3`.
+
+console.log(
+  await serverRenderer.renderToString(
+    toJsxRuntime(h('h1', 'hi!'), {
+      Fragment,
+      jsx,
+      jsxs,
+      elementAttributeNameCase: 'html'
+    })
+  )
+)
+```
+
+Yields:
+
+```html
+<h1>hi!</h1>
+```
+
+In a browser,
+do:
+
+```js
+import {h} from 'https://esm.sh/hastscript@9'
+import {toJsxRuntime} from 'https://esm.sh/hast-util-to-jsx-runtime@2'
+import {createApp} from 'https://esm.sh/vue@3'
+import {Fragment, jsx, jsxs} from 'https://esm.sh/vue@3/jsx-runtime'
+
+createApp(Component).mount('#root')
+
+function Component() {
+  return toJsxRuntime(h('h1', 'hi!'), {
+    Fragment,
+    jsx,
+    jsxs,
+    elementAttributeNameCase: 'html'
+  })
+}
+```
+
+To add better type support,
+register a global JSX namespace:
+
+```ts
+import type {JSX as Jsx} from 'vue/jsx-runtime'
+
+declare global {
+  namespace JSX {
+    type ElementClass = Jsx.ElementClass
+    type Element = Jsx.Element
+    type IntrinsicElements = Jsx.IntrinsicElements
+  }
+}
+```
+
+## Syntax
+
+HTML is parsed according to WHATWG HTML (the living standard),
+which is also followed by browsers such as Chrome,
+Firefox,
+and Safari.
+
+## 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,
+`hast-util-to-jsx-runtime@2`,
+compatible with Node.js 16.
+
+## Security
+
+Be careful with user input in your hast tree.
+Use [`hast-util-santize`][github-hast-util-sanitize] to make hast trees safe.
