+
+This project is useful when you want to support task lists in markdown.
+
+You can use these extensions when you are working with [`micromark`][micromark].
+To support all GFM features, use
+[`micromark-extension-gfm`][micromark-extension-gfm].
+
+When you need a syntax tree, you can combine this package with
+[`mdast-util-gfm-task-list-item`][mdast-util-gfm-task-list-item].
+
+All these packages are used [`remark-gfm`][remark-gfm], which focusses on making
+it easier to transform content by abstracting these internals away.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 16+), install with [npm][]:
+
+```sh
+npm install micromark-extension-gfm-task-list-item
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {gfmTaskListItem, gfmTaskListItemHtml} from 'https://esm.sh/micromark-extension-gfm-task-list-item@2'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+<script type="module">
+  import {gfmTaskListItem, gfmTaskListItemHtml} from 'https://esm.sh/micromark-extension-gfm-task-list-item@2?bundle'
+</script>
+```
+
+## Use
+
+```js
+import {micromark} from 'micromark'
+import {
+  gfmTaskListItem,
+  gfmTaskListItemHtml
+} from 'micromark-extension-gfm-task-list-item'
+
+const output = micromark('* [x] a\n* [ ] b', {
+  extensions: [gfmTaskListItem()],
+  htmlExtensions: [gfmTaskListItemHtml()]
+})
+
+console.log(output)
+```
+
+Yields:
+
+```html
+<ul>
+<li><input type="checkbox" disabled="" checked="" /> a</li>
+<li><input type="checkbox" disabled="" /> b</li>
+</ul>
+```
+
+## API
+
+This package exports the identifiers [`gfmTaskListItem`][api-gfm-task-list-item]
+and [`gfmTaskListItemHtml`][api-gfm-task-list-item-html].
+There is no default export.
+
+The export map supports the [`development` condition][development].
+Run `node --conditions development module.js` to get instrumented dev code.
+Without this condition, production code is loaded.
+
+### `gfmTaskListItem()`
+
+Create an HTML extension for `micromark` to support GFM task list items
+syntax.
+
+###### Returns
+
+Extension for `micromark` that can be passed in `extensions`, to enable GFM
+task list items syntax ([`Extension`][micromark-extension]).
+
+### `gfmTaskListItemHtml()`
+
+Create an HTML extension for `micromark` to support GFM task list items when
+serializing to HTML.
+
+###### Returns
+
+Extension for `micromark` that can be passed in `htmlExtensions` to support GFM
+task list items when serializing to HTML
+([`HtmlExtension`][micromark-html-extension]).
+
+## Authoring
+
+It is recommended to use lowercase `x` (instead of uppercase `X`), because in
+markdown, it is more common to use lowercase in places where casing does not
+matter.
+It is also recommended to use a space (instead of a tab), as there is no benefit
+of using tabs in this case.
+
+## HTML
+
+Checks relate to the `<input>` element, in the checkbox state (`type=checkbox`),
+in HTML.
+See [*§ 4.10.5.1.15 Checkbox state (`type=checkbox`)*][html-input-checkbox]
+in the HTML spec for more info.
+
+```html
+<!--…-->
+<li><input type="checkbox" disabled="" /> foo</li>
+<li><input type="checkbox" disabled="" checked="" /> bar</li>
+<!--…-->
+```
+
+## CSS
+
+GitHub itself uses slightly different markup for task list items than they
+define in their spec.
+When following the spec, as this extension does, only inputs are added.
+They can be styled with the following CSS:
+
+```css
+input[type="checkbox"] {
+  margin: 0 .2em .25em -1.6em;
+  vertical-align: middle;
+}
+
+input[type="checkbox"]:dir(rtl) {
+  margin: 0 -1.6em .25em .2em;
+}
+```
+
+For the complete actual CSS see
+[`sindresorhus/github-markdown-css`][github-markdown-css].
+
+## Syntax
+
+Checks form with the following BNF:
+
+```bnf
+gfm_task_list_item_check ::= '[' (0x09 | ' ' | 'X' | 'x') ']'
+```
+
+The check is only allowed at the start of the first paragraph, optionally
+following zero or more definitions or a blank line, in a list item.
+The check must be followed by whitespace (`[\t\n\r ]*`), which is in turn
+followed by non-whitespace.
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It exports no additional types.
+
+## 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,
+`micromark-extension-gfm-task-list-item@^2`, compatible with Node.js 16.
+
+This package works with `micromark` version `3` and later.
+
+## Security
+
+This package is safe.
