+
+## What is this?
+
+This package contains two extensions that add support for GFM footnote syntax
+in markdown to [mdast][].
+These extensions plug into
+[`mdast-util-from-markdown`][mdast-util-from-markdown] (to support parsing
+footnotes in markdown into a syntax tree) and
+[`mdast-util-to-markdown`][mdast-util-to-markdown] (to support serializing
+footnotes in syntax trees to markdown).
+
+GFM footnotes were [announced September 30, 2021][post] but are not specified.
+Their implementation on github.com is currently buggy.
+The bugs have been reported on [`cmark-gfm`][cmark-gfm].
+
+## When to use this
+
+You can use these extensions when you are working with
+`mdast-util-from-markdown` and `mdast-util-to-markdown` already.
+
+When working with `mdast-util-from-markdown`, you must combine this package
+with [`micromark-extension-gfm-footnote`][micromark-extension-gfm-footnote].
+
+When you don’t need a syntax tree, you can use [`micromark`][micromark]
+directly with `micromark-extension-gfm-footnote`.
+
+When you are working with syntax trees and want all of GFM, use
+[`mdast-util-gfm`][mdast-util-gfm] instead.
+
+All these packages are used [`remark-gfm`][remark-gfm], which
+focusses on making it easier to transform content by abstracting these
+internals away.
+
+This utility does not handle how markdown is turned to HTML.
+That’s done by [`mdast-util-to-hast`][mdast-util-to-hast].
+If your content is not in English, you should configure that utility.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 16+), install with [npm][]:
+
+```sh
+npm install mdast-util-gfm-footnote
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {gfmFootnoteFromMarkdown, gfmFootnoteToMarkdown} from 'https://esm.sh/mdast-util-gfm-footnote@2'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+<script type="module">
+  import {gfmFootnoteFromMarkdown, gfmFootnoteToMarkdown} from 'https://esm.sh/mdast-util-gfm-footnote@2?bundle'
+</script>
+```
+
+## Use
+
+Say our document `example.md` contains:
+
+```markdown
+Hi![^1]
+
+[^1]: big note
+```
+
+…and our module `example.js` looks as follows:
+
+```js
+import fs from 'node:fs/promises'
+import {fromMarkdown} from 'mdast-util-from-markdown'
+import {toMarkdown} from 'mdast-util-to-markdown'
+import {gfmFootnote} from 'micromark-extension-gfm-footnote'
+import {gfmFootnoteFromMarkdown, gfmFootnoteToMarkdown} from 'mdast-util-gfm-footnote'
+
+const doc = await fs.readFile('example.md')
+
+const tree = fromMarkdown(doc, {
+  extensions: [gfmFootnote()],
+  mdastExtensions: [gfmFootnoteFromMarkdown()]
+})
+
+console.log(tree)
+
+const out = toMarkdown(tree, {extensions: [gfmFootnoteToMarkdown()]})
+
+console.log(out)
+```
+
+…now running `node example.js` yields (positional info removed for brevity):
+
+```js
+{
+  type: 'root',
+  children: [
+    {
+      type: 'paragraph',
+      children: [
+        {type: 'text', value: 'Hi!'},
+        {type: 'footnoteReference', identifier: '1', label: '1'}
+      ]
+    },
+    {
+      type: 'footnoteDefinition',
+      identifier: '1',
+      label: '1',
+      children: [
+        {type: 'paragraph', children: [{type: 'text', value: 'big note'}]}
+      ]
+    }
+  ]
+}
+```
+
+```markdown
+Hi\![^1]
+
+[^1]: big note
+```
+
+## API
+
+This package exports the identifiers
+[`gfmFootnoteFromMarkdown`][api-gfmfootnotefrommarkdown] and
+[`gfmFootnoteToMarkdown`][api-gfmfootnotetomarkdown].
+There is no default export.
+
+### `gfmFootnoteFromMarkdown()`
+
+Create an extension for
+[`mdast-util-from-markdown`][mdast-util-from-markdown]
+to enable GFM footnotes in markdown.
+
+###### Returns
+
+Extension for `mdast-util-from-markdown`
+([`FromMarkdownExtension`][frommarkdownextension]).
+
+### `gfmFootnoteToMarkdown()`
+
+Create an extension for
+[`mdast-util-to-markdown`][mdast-util-to-markdown]
+to enable GFM footnotes in markdown.
+
+###### Returns
+
+Extension for `mdast-util-to-markdown`
+([`ToMarkdownExtension`][tomarkdownextension]).
+
+## HTML
+
+This utility does not handle how markdown is turned to HTML.
+That’s done by [`mdast-util-to-hast`][mdast-util-to-hast].
+If your content is not in English, you should configure that utility.
+
+## Syntax
+
+See [Syntax in `micromark-extension-gfm-footnote`][syntax].
+
+## Syntax tree
+
+The following interfaces are added to **[mdast][]** by this utility.
+
+### Nodes
+
+#### `FootnoteDefinition`
+
+```idl
+interface FootnoteDefinition <: Parent {
+  type: 'footnoteDefinition'
+  children: [FlowContent]
+}
+
+FootnoteDefinition includes Association
+```
+
+**FootnoteDefinition** (**[Parent][dfn-parent]**) represents content relating
+to the document that is outside its flow.
+
+**FootnoteDefinition** can be used where **[flow][dfn-flow-content]** content
+is expected.
+Its content model is also **[flow][dfn-flow-content]** content.
+
+**FootnoteDefinition** includes the mixin
+**[Association][dfn-mxn-association]**.
+
+**FootnoteDefinition** should be associated with
+**[FootnoteReferences][dfn-footnote-reference]**.
+
+For example, the following markdown:
+
+```markdown
+[^alpha]: bravo and charlie.
+```
+
+Yields:
+
+```js
+{
+  type: 'footnoteDefinition',
+  identifier: 'alpha',
+  label: 'alpha',
+  children: [{
+    type: 'paragraph',
+    children: [{type: 'text', value: 'bravo and charlie.'}]
+  }]
+}
+```
+
+#### `FootnoteReference`
+
+```idl
+interface FootnoteReference <: Node {
+  type: 'footnoteReference'
+}
+
+FootnoteReference includes Association
+```
+
+**FootnoteReference** (**[Node][dfn-node]**) represents a marker through
+association.
+
+**FootnoteReference** can be used where
+**[phrasing][dfn-phrasing-content]** content is expected.
+It has no content model.
+
+**FootnoteReference** includes the mixin **[Association][dfn-mxn-association]**.
+
+**FootnoteReference** should be associated with a
+**[FootnoteDefinition][dfn-footnote-definition]**.
+
+For example, the following markdown:
+
+```markdown
+[^alpha]
+```
+
+Yields:
+
+```js
+{
+  type: 'footnoteReference',
+  identifier: 'alpha',
+  label: 'alpha'
+}
+```
+
+### Content model
+
+#### `FlowContent` (GFM footnotes)
+
+```idl
+type FlowContentGfm = FootnoteDefinition | FlowContent
+```
+
+#### `PhrasingContent` (GFM footnotes)
+
+```idl
+type PhrasingContentGfm = FootnoteReference | PhrasingContent
+```
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It does not export additional types.
+
+The `FootnoteDefinition` and `FootnoteReference` types of the mdast nodes are
+exposed from `@types/mdast`.
+
+## 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,
+`mdast-util-gfm-footnote@^2`, compatible with Node.js 16.
