+
+## What is this?
+
+This package is a small utility that checks that a node is a certain element.
+
+## When should I use this?
+
+Use this small utility if you find yourself repeating code for checking what
+elements nodes are.
+
+A similar package, [`unist-util-is`][unist-util-is], works on any unist node.
+
+For more advanced tests, [`hast-util-select`][hast-util-select] can be used
+to match against CSS selectors.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 16+), install with [npm][]:
+
+```sh
+npm install hast-util-is-element
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {isElement} from 'https://esm.sh/hast-util-is-element@3'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+<script type="module">
+  import {isElement} from 'https://esm.sh/hast-util-is-element@3?bundle'
+</script>
+```
+
+## Use
+
+```js
+import {isElement} from 'hast-util-is-element'
+
+isElement({type: 'text', value: 'foo'}) // => false
+isElement({type: 'element', tagName: 'a', properties: {}, children: []}) // => true
+isElement({type: 'element', tagName: 'a', properties: {}, children: []}, 'a') // => true
+isElement({type: 'element', tagName: 'a', properties: {}, children: []}, 'b') // => false
+isElement({type: 'element', tagName: 'a', properties: {}, children: []}, ['a', 'area']) // => true
+```
+
+## API
+
+This package exports the identifiers
+[`convertElement`][api-convert-element] and
+[`isElement`][api-is-element].
+There is no default export.
+
+### `isElement(element[, test[, index, parent[, context]]])`
+
+Check if `element` is an `Element` and whether it passes the given test.
+
+###### Parameters
+
+*   `element` (`unknown`, optional)
+    — thing to check, typically [`Node`][hast-node]
+*   `test` ([`Test`][api-test], optional)
+    — check for a specific element
+*   `index` (`number`, optional)
+    — position of `element` in its parent
+*   `parent` ([`Parent`][hast-parent], optional)
+    — parent of `element`
+*   `context` (`unknown`, optional)
+    — context object (`this`) to call `test` with
+
+###### Returns
+
+Whether `element` is an `Element` and passes a test (`boolean`).
+
+###### Throws
+
+When an incorrect `test`, `index`, or `parent` is given.
+There is no error thrown when `element` is not a node or not an element.
+
+### `convertElement(test)`
+
+Generate a check from a test.
+
+Useful if you’re going to test many nodes, for example when creating a
+utility where something else passes a compatible test.
+
+The created function is a bit faster because it expects valid input only:
+a `element`, `index`, and `parent`.
+
+###### Parameters
+
+*   `test` ([`Test`][api-test], optional)
+    — a test for a specific element
+
+###### Returns
+
+A check ([`Check`][api-check]).
+
+### `Check`
+
+Check that an arbitrary value is an element (TypeScript type).
+
+###### Parameters
+
+*   `this` (`unknown`, optional)
+    — context object (`this`) to call `test` with
+*   `element` (`unknown`)
+    — anything (typically an element)
+*   `index` (`number`, optional)
+    — position of `element` in its parent
+*   `parent` ([`Parent`][hast-parent], optional)
+    — parent of `element`
+
+###### Returns
+
+Whether this is an element and passes a test (`boolean`).
+
+### `Test`
+
+Check for an arbitrary element (TypeScript type).
+
+*   when `string`, checks that the element has that tag name
+*   when `function`, see  [`TestFunction`][api-test-function]
+*   when `Array`, checks if one of the subtests pass
+
+###### Type
+
+```ts
+type Test =
+  | Array<TestFunction | string>
+  | TestFunction
+  | string
+  | null
+  | undefined
+```
+
+### `TestFunction`
+
+Check if an element passes a test (TypeScript type).
+
+###### Parameters
+
+*   `element` ([`Element`][hast-element])
+    — an element
+*   `index` (`number` or `undefined`)
+    — position of `element` in its parent
+*   `parent` ([`Parent`][hast-parent] or `undefined`)
+    — parent of `element`
+
+###### Returns
+
+Whether this element passes the test (`boolean`, optional).
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It exports the additional types [`Check`][api-check],
+[`Test`][api-test], and
+[`TestFunction`][api-test-function].
+
+## 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-is-element@^3`,
+compatible with Node.js 16.
+
+## Security
+
+`hast-util-is-element` does not change the syntax tree so there are no openings
+for [cross-site scripting (XSS)][xss] attacks.
